+In order to clarify the intellectual property license granted with Contributions from any person or entity, Remotely Save dev team ("Remotely Save") must have on file a signed Contributor License Agreement ("CLA") from each Contributor, indicating agreement with the license terms below. This agreement is for your protection as a Contributor as well as the protection of Remotely Save and its users. It does not change your rights to use your own Contributions for any other purpose.
+
+You accept and agree to the following terms and conditions for Your Contributions (present and future) that you submit to Remotely Save. Except for the license granted herein to Remotely Save and recipients of software distributed by Remotely Save, You reserve all right, title, and interest in and to Your Contributions.
+
+1. Definitions.
+
+   "You" (or "Your") shall mean the copyright owner or legal entity authorized by the copyright owner that is making this Agreement with Remotely Save. For legal entities, the entity making a Contribution and all other entities that control, are controlled by, or are under common control with that entity are considered to be a single Contributor. For the purposes of this definition, "control" means (i) the power, direct or indirect, to cause the direction or management of such entity, whether by contract or otherwise, or (ii) ownership of fifty percent (50%) or more of the outstanding shares, or (iii) beneficial ownership of such entity.
+
+   "Contribution" shall mean any original work of authorship, including any modifications or additions to an existing work, that is intentionally submitted by You to Remotely Save for inclusion in, or documentation of, any of the products owned or managed by Remotely Save (the "Work"). For the purposes of this definition, "submitted" means any form of electronic, verbal, or written communication sent to Remotely Save or its representatives, including but not limited to communication on electronic mailing lists, source code control systems, and issue tracking systems that are managed by, or on behalf of, Remotely Save for the purpose of discussing and improving the Work, but excluding communication that is conspicuously marked or otherwise designated in writing by You as "Not a Contribution."
+
+2. Grant of Copyright License. Subject to the terms and conditions of this Agreement, You hereby grant to Remotely Save and to recipients of software distributed by Remotely Save a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable copyright license to reproduce, prepare derivative works of, publicly display, publicly perform, sublicense, and distribute Your Contributions and such derivative works.
+
+3. Grant of Patent License. Subject to the terms and conditions of this Agreement, You hereby grant to Remotely Save and to recipients of software distributed by Remotely Save a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable (except as stated in this section) patent license to make, have made, use, offer to sell, sell, import, and otherwise transfer the Work, where such license applies only to those patent claims licensable by You that are necessarily infringed by Your Contribution(s) alone or by combination of Your Contribution(s) with the Work to which such Contribution(s) was submitted. If any entity institutes patent litigation against You or any other entity (including a cross-claim or counterclaim in a lawsuit) alleging that your Contribution, or the Work to which you have contributed, constitutes direct or contributory patent infringement, then any patent licenses granted to that entity under this Agreement for that Contribution or Work shall terminate as of the date such litigation is filed.
+
+4. You represent that you are legally entitled to grant the above license. If your employer(s) has rights to intellectual property that you create that includes your Contributions, you represent that you have received permission to make Contributions on behalf of that employer, that your employer has waived such rights for your Contributions to Remotely Save, or that your employer has executed a separate Corporate CLA with Remotely Save.
+
+5. You represent that each of Your Contributions is Your original creation (see section 7 for submissions on behalf of others). You represent that Your Contribution submissions include complete details of any third-party license or other restriction (including, but not limited to, related patents and trademarks) of which you are personally aware and which are associated with any part of Your Contributions.
+
+6. You are not expected to provide support for Your Contributions, except to the extent You desire to provide support. You may provide support for free, for a fee, or not at all. Unless required by applicable law or agreed to in writing, You provide Your Contributions on an "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied, including, without limitation, any warranties or conditions of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE.
+
+7. Should You wish to submit work that is not Your original creation, You may submit it to Remotely Save separately from any Contribution, identifying the complete details of its source and of any license or other restriction (including, but not limited to, related patents, trademarks, and license agreements) of which you are personally aware, and conspicuously marking the work as "Submitted on behalf of a third-party: [named here]".
+
+8. You agree to notify Remotely Save of any facts or circumstances of which you become aware that would make these representations inaccurate in any respect.

+Starting from April 29, 2024, all individual contributors' contributions are only possibly accepted after they sign the CLA.

-
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes

-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
-
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and

-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.

+
+1. Anyway, security is a hard problem. The author of Remotely Save doesn't have sufficient knowledge to "judge" which one is the better format. **Use them at your own risk.**
+2. Currently the RClone Crypt format is recommended by default in Remotely Save. Just because of the taste from the Remotely Save author, who likes RClone.
+3. **Always use a long password.**
+4. Both algorithms are selected deliberately to **be compatible with some well-known third-party tools** (instead of some home-made methods) and **have many tests to ensure the correctness**.

+
+## Steps of subscribing to some features. 
+
+1. Firstly please visit your [profile page](https://remotelysave.com/user/profile) online.
+2. You can subscribe to some features. Prices vary.
+    ![PRO features online](./pro_features_enabled_on_website.png)

+    ![check again PRO features](./check_pro_features_in_settings.png)
+4. Sync and enjoy your PRO features!
+
+## Why so complicated?
+
+Because we doesn't have payment method inside the plugin, so we have to:
+
+* build a website, 
+* require users having online accounts
+* and connect the plugin to the online account.
+
+Moreover, an online account allows flexibe management of subscriptions.

+7. A notice will tell you that you've connected or not.
+8. Sync! The plugin will create a vault folder in the root of your Google Drive and upload notes into that folder.
+9. **Read the caveats below.**
+
+# Why so complicated?
+
+Because Google Drive's api doesn't fit into the special envorinment of Obsidian plugin. So we need a website.
+
+# The credential
+
+The website does **NOT** store or save the Google drive credential (the code you obtian in the end of the flow). The website is just a "bridge" to help you obtain that code, and just manage your subscription to PRO features.
+
+But please be aware that the code is saved locally in your Obsidian. It works like a special password. So that the plugin can upload or download or modify the files for you.
+
+# The caveats
+
+* As of June 2024, this feature is in beta stage. **Back up your vault before using this feature.**
+
+* The plugin can **only** sees, reads or writes the files and folders created by itself! 
+
+    It means that, you CANNOT manually create the vault folder in your Google Drive account. And if you manually upload any files using Google's official website, the plugin does **NOT** see them. All operations must go through Obsidian and uploaded by the plugin.
+
+    You can, however, view, and download the files on Google Drive [official web page](https://drive.google.com/drive/u/0/my-drive).
+
+    Precisely speaking, the plugin applies for the `drive.file` scope recommended by Google. See [the doc](https://developers.google.com/drive/api/guides/api-specific-auth#benefits) by Google for the scope's benefits. Basically the plugin will never (is unable to) mess up your other files or folders.
+
+    Moreover, this scope is "not-sensitive", so that the plugin doesn't need to go through Google's complicated verification process while applying for it.
+
+* Google Drive, unlike other cloud storage, allows files of same name co-existing in the same folder! (hmmmmm...) It may or may not make the plugin stop working. Users might need to remove the duplicated file manually on Google's official website.

+# OneDrive
+
+- **This plugin is NOT an official Microsoft / OneDrive product.** The plugin just uses Microsoft's [OneDrive's public API](https://docs.microsoft.com/en-us/onedrive/developer/rest-api).
+- After the authorization, the plugin can read your name and email, and read and write files in your OneDrive's `/Apps/remotely-save` folder.
+- If you decide to authorize this plugin to connect to OneDrive, please go to plugin's settings, and choose OneDrive then follow the instructions.
+- Password-based end-to-end encryption is also supported. But please be aware that **the vault name itself is not encrypted**.
+- If you want to sync the files across multiple devices, **your vault name should be the same** while using default settings.
+
+## FAQ
+
+### How about OneDrive for Business?
+
+This plugin only works for "OneDrive for personal", and not works for "OneDrive for Business" (yet). See [#11](https://github.com/fyears/remotely-save/issues/11) to further details.
+
+### I cannot find `/Apps/remotely-save` folder
+
+Mystically some users report that their OneDrive generate `/Application/Graph` instead of `/Apps/remotely-save`. See [#517](https://github.com/remotely-save/remotely-save/issues/517).
+
+The solution is simple:
+
+1. Backup your vault manually.
+2. Go to onedrive website (<https://onedrive.live.com/>), and rename `/Application/Graph` to `/Application/remotely-save` (right click on the folder and you will see rename option)
+3. Come back to Obsidian and try to sync!

+* pCloud's API seems to not allow uploading empty files. You can choose to skip them or raise errors in Remotely Save plugin's settings.
+
+# Why not use webdav?
+
+1. pCloud only provides webdav for Premium. If you are a Premium user, you can still use pCloud webdav with Remotely Save.
+2. The Remotely Save PRO feture "sync with pCloud" is developed using pCloud's native API, instead of webdav interface. It brings benefits such that the last modified time can be preserved.

+    * The docker version <https://github.com/nextcloud/docker> for internal network, and [Caddy as reverse proxy](https://caddyserver.com/docs/quick-starts/reverse-proxy) (for https), are personally recommended.
+    * If you find installing Nextcloud by yourselves is difficult, you can find some "Nextcloud's trusted, certified providers" on [Nextcloud Sign up page](https://nextcloud.com/sign-up/); For example, [The Good Cloud](https://thegood.cloud/) there generously provides 2 GB free stoarage space.
+    * Remotely Save is tested to be working with the docker version and The Good Cloud.
+2. Go to Nextcloud's settings. Find the webdav url (something like `https://cloud.example.com/remote.php/dav/files/USERNAME`). Use this (without tailing slash), and your account and your password, in Remotely Save.

+## Attention
+
+The tutorial author (the author of Remotely Save) is NOT an expert of NAS / Synology. Please read the doc carefully and change it to accommodate your needs by yourself.
+
+**It's dangerous to expose your NAS into public Internet if you don't know how to set up firewalls and other protections.**
+
+## Steps
+
+Synology DSM 7 is used in this tutorial.
+
+1. Create a new shared folder if you don't have one. For this tutorial, a new shared folder `share2` is created. You should assing a proper user to read / write the shared folder.
+   ![](./synology_create_shared_folder.png)
+
+2. Assuming you want to sync your vault into sub folder `哈哈哈/sub folder`, please create the sub folder(s) correspondingly inide the shared folder `share2`.
+
+3. Install webdav server from package center.
+   ![](./synology_install_webdav_server.png)
+
+4. Enter the webdav server settings.
+
+5. If you know how to configure https certificates correctly, you are strongly recommend to enable https.
+
+   For the demonstration purpose, this tutorial enable http server for the later steps.
+
+   Also "Enable DavDepthInfinity", which could speed up the plugin runnings greatly.
+
+   "Apply".
+
+   ![](./synology_webdav_server_settings.png)
+
+6. In Remotely Save settings, you should input your address as:
+
+   `http(s)://<your synology ip or domain>:<port>/<shared folder>/<sub folders>`
+
+   For example, in the tutorial, the proper url should be:
+
+   `http://<ip>:5000/share2/哈哈哈/sub folder`
+
+   Username and password should be the user you configured before with read / write permissions to `share2`.
+
+   Depth header should be "supports depth="infinity"".

+
+## 注意
+
+教程作者（Remotely Save 作者）**不是** NAS、群晖专家。请仔细阅读文档，并自行改动以适应您自身需求。
+
+**没有设置防火墙和其他保护措施的话，将 NAS 暴露到公网上非常危险。**
+
+## 步骤
+
+本教程有用到群晖 DSM 7。
+
+1. 创建共享文件夹。本教程示例创建了 `share2`。你需要允许某个账号对此的读写权限。
+
+   ![](./synology_create_shared_folder.png)
+
+2. 假设之后你想同步你的库到子文件夹，`哈哈哈/sub folder`，请先在共享文件夹 `share2` 底下创建好。
+
+3. 从套件中心安装 webdav server 。
+   ![](./synology_install_webdav_server.png)
+
+4. 进入 webdav server 设置。
+
+5. 如果你知道如何正确配置 https 证书的话，强烈建议开启 https。
+
+   本教程简化示例，开启了 http。
+
+   也设置“Enable DavDepthInfinity”，这可以加速插件连接速度。
+
+   “Apply”。
+
+   ![](./synology_webdav_server_settings.png)
+
+6. 在 Remotely Save 设置页，你的地址应如下格式输入：
+
+   `http(s)://<your synology ip or domain>:<port>/<shared folder>/<sub folders>`
+
+   比如说，本教程里，正确的地址类似于：
+
+   `http://<ip>:5000/share2/哈哈哈/sub folder`
+
+   用户名和密码是你之前配置了允许读写 `share2` 的那个账号。
+
+   Depth 设置应为“supports depth="infinity"”。

+- Webdis: <https://github.com/nicolasff/webdis>
+- Redis®: <https://redis.io/>
+
+## Explanation and Background
+
+I like the Redis® software very much, and would like to experiment using it as a "file storage". It seems to be nature by using path as the key and the content as the value (Sort of..., see below).
+
+However, Redis® works by using TCP connections, and browser js cannot establish raw TCP connections. We need a HTTP gateway, to provide the HTTP api. Wedis seems to be the most famous open source one.
+
+And of course, this method should work for Redis® alternatives: Valkey, Redict, KeyDB, Dragonfly, Garnet, ...
+
+## Disclaimer
+
+This app is NOT an official Redis® Ltd / Redis® OSS / Webdis product. Redis is a registered trademark of Redis Ltd.
+
+**Never expose your Redis® or Webdis to public without security protection!!!** You are response for protecting your server.
+
+## Usage
+
+1. Install Redis®.
+2. Install Webdis.
+3. In `webdis.json`, configure the ACL for using password and username, and / or ip filters. **Never expose your Redis® or Webdis to public without security protection!!!**.
+4. Install and configure reverse proxy, firewall, https, etc. (You have to configure HTTPS correctly if you want to use it on iOS)
+5. In Remotely Save settings, enter your server address, username, password, and adjust the "base dir". Check connection.
+6. Sync!
+7. Serveral keys and values will be generated in your Redis® database:
+
+   ```
+   rs:fs:v1:${encodeURIComponent(vaultName+'/'+folderStructure+'/'+fileName)}:meta # you can HGETALL it
+   rs:fs:v1:${encodeURIComponent(vaultName+'/'+folderStructure+'/'+fileName)}:content # you can GET it

+
+# Intro
+
+* It's a PRO feature of Remotely Save plugin.
+* **This plugin is NOT an official Yandex Disk or Yandex product, and just uses Yandex Disk's public api.**
+
+# Steps
+
+## Steps of Remotely Save subscription
+
+1. Please sign up and sign in an online account, connect your plugin to your online account firstly. See [the PRO tutorial](../../pro/README.md) firstly.
+2. Subscribe to "sync with Yandex Disk" feature online.
+3. Go back to your Remotely Save plugin inside Obsidian, click "Check again" button in PRO settings. So that the plugin knows some features are enabled. In this case, sync with Yandex Disk should be detected.
+
+## Steps of Connecting to your Yandex Disk
+
+After you enabled the PRO feature in your Remotely Save plugin, you can connect to your Yandex Disk account now.
+
+1. In Remotely Save settings, change your sync service to Yandex Disk.
+2. Click Auth, visit the link, go to Yandex Disk website to start.
+3. Follow the instruction on Yandex Disk, and allow Remotely Save to connect.
+4. You will be redirected back to Remotely Save plugin.
+5. A notice will tell you that you've connected or not.
+6. Sync! The plugin will create a vault folder in the root of your Yandex Disk and upload notes into that folder.
+7. **Read the caveats below.**
+
+# The caveats
+
+* As of June 2024, this feature is in beta stage. **Back up your vault before using this feature.**
+
+# Why not use webdav?
+
+1. The Remotely Save PRO feture "sync with Yandex Disk" is developed using Yandex Disk's native API, instead of webdav interface. It brings benefits such that the last modified time can be preserved.
+2. Some users prefer oauth2 method to authorize themselves.
+
+# Bonus: where to register the app
+
+* <https://oauth.yandex.com/client/new/> or <https://oauth.yandex.ru/client/new/>
+* redirect uri can be set to <https://oauth.yandex.com/verification_code> or <https://oauth.yandex.ru/verification_code>.

+# Sync Algorithm V3
+
+Drafted on 20240117.
+
+An absolutely better sync algorithm. Better for tracking deletions and better for subbranching.
+
+## Huge Thanks
+
+Basically a combination of algorithm v2 + [synclone](https://github.com/Jwink3101/syncrclone/blob/master/docs/algorithm.md) + [rsinc](https://github.com/ConorWilliams/rsinc) + (some of rclone [bisync](https://rclone.org/bisync/)). All of the later three are released under MIT License so no worries about the licenses.
+
+## Features
+
+Must have
+
+1. true deletion detection
+2. deletion protection (blocking) with a setting
+3. transaction from the old algorithm
+4. user warning show up, **new algorithm needs all clients to be updated!** (deliberately corrput the metadata file??)
+5. filters
+6. conflict warning
+7. partial sync
+
+Nice to have
+
+1. true time and hash
+2. conflict rename
+
+## Description
+
+We have _five_ input sources:
+
+1. local all files
+2. remote all files
+3. _local previous succeeded sync history_
+4. local deletions
+5. remote deletions.
+
+Init run, consuming remote deletions :
+
+Change history data into _local previous succeeded sync history_.
+
+Later runs, use the first, second, third sources **only**.
+
+Bidirectional table is modified based on synclone and rsinc. Incremental push / pull only tables is further modified based on the bidirectional table. The number inside the table cell is the decision branch in the code.
+
+Bidirectional:

+# Pro Features
+
+## What?
+
+Remotely Save has some "pro features", which users have to pay for using them.
+
+## Sign Up / Sign In And Connect
+
+See the tutorial about your PRO account [here](../docs/pro/README.md).
+
+## Smart Conflict
+
+Basic (free) version can detect conflicts, but users have to choose to keep newer version or larger version of the files.
+
+PRO (paid) feature "Smart Conflict" gives users one more option: merge small markdown files, or duplicate large markdown files or non-markdown files.
+
+## Sync With Google Drive
+
+PRO (paid) feature "sync with Google Drive" allows users to to sync with Google Drive. Tutorials and limitations are documented [here](../docs/remote_services/googledrive/README.md).
+
+## License
+
+The codes or files or subfolders inside the current folder (`pro` in the repo), are released under "source available" license: "PolyForm Strict License 1.0.0".
+
+Suggestions are welcome.

+
+1. `fsXxx.ts`
+2. `settingsXxx.ts`
+3. add callback and `xxxConfig` in `baseTypesPro.ts`
+4. add `xxxConfig` to `DEFAULT_SETTINGS` and `RemotelySavePluginSettings` in `main.ts`
+5. add `registerObsidianProtocolHandler`, if undefinded, `let xxxExpired`, expired notice in `main.ts`
+6. add `langs/`
+7. add css into `styles.css`
+8. general `settings.ts` add: config part, chooser, import export
+9. `generateProSettingsPart.ts`
+10. `importExport.ts`
+11. `fsGetter.ts`
+12. `sync.ts` checking for PRO: `checkProRunnableAndFixInplace`
+13. `configPersist.test.ts`
+14. `README.md` add service at menu and detail
+15. `docs/` add service

+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of

+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
