-
-      "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

-      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:
-

-      (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.

+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.
+    ![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.

+# Google Drive (PRO)

+
+* 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.

+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.

+1. Install, or find a hosted version. 
+    * 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.

+# 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.

+      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.
