+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.

-      form, that is based on (or derived from) the Work and for which the

-      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

-          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.

 - In auto sync mode, if any error occurs, the plugin would **fail silently**.
 - Auto sync only works when Obsidian is being opened. It's **technically impossible** to auto sync while Obsidian is in background, because the plugin just works in the browser environment provided by Obsidian.

 ## How To Deal With Hidden Files Or Folders
 
 **By default, all files or folder starting with `.` (dot) or `_` (underscore) are treated as hidden files, and would NOT be synced.** It's useful if you have some files just staying locally. But this strategy also means that themes / other plugins / settings of this plugin would neither be synced.
 
 In the latest version, you can change the settings to allow syncing `_` files or folders, as well as `.obsidian` special config folder (but not any other `.` files or folders).

+
+## Steps of subscribing to some features. 
+

+    ![check again PRO features](./check_pro_features_in_settings.png)
+4. Sync and enjoy your PRO features!
+
+## Why so complicated?
+
+Because we don't have a 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 flexible management of subscriptions.

+# Azure Blob Storage (GDrive) (PRO)
+
+# Intro
+
+* It's a PRO feature of Remotely Save plugin.
+* **This plugin is NOT an official Microsoft / Azure product, and just uses Azure Blob Storage's public api.**
+
+# Disclaimer
+
+I (author of Remotely Save) is **NOT** an expert of Azure products. The tutorials here are for references only. Azure products are very complex.
+
+***As far as the law allows, the software (Remotely Save) comes as is, without any warranty or condition, and the licensor will not be liable to you for any damages arising out of these terms or the use or nature of the software, under any kind of legal claim.***
+
+# Steps
+
+Please read through the following steps before you actually connect.
+
+## Preparation In Azure Blob Storage Side
+
+You only need to do this **once**, before the Container SAS Url expires in the future.
+
+In short, you need to: configure CORS and configure a policy and cobtain a Container SAS Url.
+
+1. Connect to the service:
+    
+    Download Microsoft's free [Azure Storage Explorer](https://azure.microsoft.com/en-us/products/storage/storage-explorer). The following tutorial uses this app. Actually you may be able to find the same settings on Azure official website.
+    
+    Use this app to connect to your Blob Storage service or account.
+    
+2. CORS:
+    
+    Right click on `Blob containers`, click "configure CORS". Add a rule, enter the following and save:
+    ```
+    Allowed Origins: *
+    Allowed Methods: DELETE,GET,HEAD,MERGE,POST,PATCH,OPTIONS,PUT
+    Allowed Headers: x-ms-*, content-type
+    Exposed Headers: x-ms-*, content-type
+    Max Age (in seconds): 5
+    ```
+
+    ![CORS screenshot](./azure_cors.png)
+
+3. Create the container:  
+    
+    Create the container if you don't have one. In this tutorial, we use `example-container`.
+
+    ![container screenshot](./azure_example_container.png)
+
+4. Generate a policy:
+    
+    * Right click on you container, click "Manage Stored Access Policies". 
+    * Choose your id, for example `example-container-0000001`.
+    * Change to Expiry time to an appropriate date. **By default it is only valid for a week.** After its expiration, you need come back and adjust the expiry date again! In this tutorial, we set it to a year.
+    * And allow these methods: Read, Add, Create, Write, Delete, List.
+    * Save
+   
+    Read Microsoft's official [doc](https://learn.microsoft.com/en-us/rest/api/storageservices/define-stored-access-policy) for more info. The main benefit of generating an access policy is easier revocation of SAS Url if anything goes bad. 
+
+    ![Manage Stored Access Policies screenshot](./azure_policy_1.png)
+    ![Add Policy screenshot](./azure_policy_3.png)
+
+5. Generate a Container SAS Url:
+
+    Then we want to create a container level SAS (shared access signature) url.
+
+    * Right click on you container, click "Get Shared Access Signature". 
+    * In access policy, choose the previous one you created: for example `example-container-0000001`.
+    * Save the setting
+    * You will see a url is generated, which starts with `https://` or `http://`. It should looks like `https://<account>.blob.core.windows.net/<container name>?sv=...&sig=...`
+    * Save the Container SAS Url somewhere, and you will need this later.
+
+    Read Microsoft's official [doc](https://learn.microsoft.com/en-us/azure/storage/common/storage-sas-overview) for more info.
+
+    ![Container SAS Url screenshot 1](./azure_sas_1.png)
+    ![Container SAS Url screenshot 2](./azure_sas_2.png)
+    
+### Why so complicated in Azure settings?
+
+Because Azure Blob Storage's api has some limitation in browser environment, so we need to configure CORS and SAS. Because we want to revoke the SAS when needed, we need to use a policy.
+
+### Revocation
+
+If you suspect someone read the resource unexpectedly, you can revoke the SAS by changing the name or expiry date of the policy. And generate the SAS Url again.
+
+## 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 Azure Blob Storage" 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 Azure Blob Storage should be detected.
+
+## Steps of Connecting to your Azure Blob Storage
+
+After you enabled the PRO feature in your Remotely Save plugin, **and prepared the Container SAS Url**, you can connect to your Azure Blob Storage account now.
+
+1. In Remotely Save settings, change your sync service to Azure Blob Storage.
+2. Input your Container SAS Url
+3. Input your container name.
+4. By default, the plugin will save your vault remotely with a prefix `<your vault name>/`. You can change the prefix. No prefix is not allowed.
+5. Check the connection. A notice will tell you that you've connected or not.
+7. Sync! The plugin will upload the fils and "folders" of your vault into your Azure Blob Storage with the preix.
+8. **Read the caveats below.**
+
+![RS setting screenshot](./azure_rs_setting.png)
+
+# The caveats
+
+* As of June 2024, this feature is in alpha stage. **Back up your vault before using this feature.**

+
+# Intro
+
+* It's a PRO feature of Remotely Save plugin.
+* **This plugin is NOT an official Google product, and just uses Google Drive'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 Google Drive" feature online.

+
+## Steps of Connecting to your Google Drive

+After you enabled the PRO feature in your Remotely Save plugin, you can connect to your Google Drive account now.
+
+1. In Remotely Save settings, change your sync service to Google Drive.

+4. Follow the instruction on Google website, and allow (continue) Remotely Save to connect.
+    ![allow Remotely Save in Google website](./google_drive_auth_allow.png)
+5. You will be redirected to Remotely Save website, and you will get a code. Copy it...
+    ![redirected back and get the code](./google_drive_auth_code_show.png)
+6. ... And paste the code back to the plugin inside Obsidian. Click submit.
+    ![submit the code in setting](./google_drive_code_submit.png)
+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.

+# Apache Webdav 
+
+The following tutorial uses Apache with Docker in Linux, using the image [`bytemark/webdav`](https://hub.docker.com/r/bytemark/webdav/).
+
+You can also checkout the official doc from Bytemark [here](https://docs.bytemark.co.uk/article/run-your-own-webdav-server-with-docker/). The tutorial you are reading here is a little different from Bytemark's article.
+
+Assuming you want a webdav server on Linux satisfying that:
+
+1. Data is saved in your host machine's `./dav1` folder,
+2. WebDAV is accessed by a user `user1` with password `password1`,
+3. WebDAV is accessed on the host machine and port 8080: `127.0.0.1:8080`.
+4. Use Basic auth type.
+
+Install docker nd set its permission properly. Then run this in terminal:
+
+```bash
+mkdir ./dav1 # create the local folder
+
+docker container run --rm \
+  -p 127.0.0.1:8080:80 \
+  -v ./dav1:/var/lib/dav \
+  -e USERNAME=user1 \
+  -e PASSWORD=password1 \
+  -e AUTH_TYPE=Basic \
+  bytemark/webdav
+```
+
+We do not have `--detach` prameter here, so the server will be closed as soon as you terminate the program or close terminal. You might want to adjust the settings further by yourself.
+
+Then, in Remotely Save's setting, set these (auth type should always be `Basic`):
+
+```
+Server: http://127.0.0.1:8080
+User: user1
+Password: password1
+Auth Type: Basic
+Depth Header Sent To Servers: only supports depth='1'
+```
+
+![Apache RS Setting](./apache_rs_settings.png)
+
+Then the server should be connected! You can sync now!
+
+In you host machine's file system, you should find some files and folders were added into the folder `./dav1`.
+
+```
+ls ./dav1/
+## data  DavLock  DavLock.dir  DavLock.pag
+
+ls ./dav1/data/
+## <your vault name or your base dir>
+```
+
+# Auth type
+
+You can change the auth type while calling Docker, between `Basic` and `Digest`. And please rememberto adjust the Remotely Save's settings. Both works.
+
+# Notice
+
+1. **Never expose your webdav server to public networks without protections or without strong passwords!**
+2. I personally recommend using tailscale to build a LAN instead of expoing the service to public.
+3. If you want to connect to the server from iOS (iPhone / iPad), the https is required. I personally recommend using caddy as the reverse proxy. Caddy can also be combined with tailscale.

+
+      "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

+
+   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.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
