+The plugin is developed for the browser environment. The "fake" browser behind the scenes also follows the CORS policy.
+
+[MDN has a doc about CORS.](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS)
+
+From Obsidian desktop >= 0.13.25 or mobile >= 1.1.1, Obsidian [provides a new API `requiestUrl`](https://forum.obsidian.md/t/obsidian-release-v0-13-25-insider-build/32701), that allows the plugin to fully bypass the CORS issue. As of Mar 2022, the latest public-released Obsidian desktop has supported this API, but the Obsidian mobile still stays in insider.
+
+For using this plugin in Obsidian desktop < 0.13.25 or mobile < 1.1.1, we need to configure the server side to return the header `Access-Control-Allow-Origin` allowing the origins `app://obsidian.md` and `capacitor://localhost` and `http://localhost`.

+# Limitations From The Browser Environment: No Node.js
+
+To support the mobile Obsidian, the plugin is limited to be developed for the browser environment, instead of the Node.js environment.
+
+Many js libraries are designed to work in both the browser and the Node.js environments. But some are not, because the browser doesn't provide the corresponding abilities.
+
+For example, there is a popular npm package [`ssh2-sftp-client`](https://www.npmjs.com/package/ssh2-sftp-client) for SFTP. But it relies on the modules (e.g. `http`) from Node.js which cannot be "translated" to the browser environment. So it's impossible to make this plugin support SFTP. The same status applies to FTP / FTPS.
+
+Likewise, [MEGA](https://mega.nz/) provides a SDK, but the SDK is [for C++ only](https://mega.nz/doc), so it's also impossible to make this plugin support MEGA.

+## Material Source
+
+To apply for the production use of Dropbox API, some descriptions are needed to be submitted to Dropbox. Coincidently, this can also be served as a "readme" to use this plugin with Dropbox.
+
+## Some Backgrounds
+
+1. Obsidian allows users to take notes using markdown files.
+2. The "app", remotely-save. is an unofficial Obsidian plugin, helping users download and upload ("sync") their notes from and to Dropbox.
+3. Technically, remotely-save is developed using web technologies.
+
+## Api Usages
+
+1. remotely-save uses "App folder", to avoid unnecessary accessing users' other files.
+2. remotely-save uses "account_info.read", to get the displayed username, so that users know which of their accounts has been logged in after OAuth steps.
+3. remotely-save uses "files.content.read", so that it can read the "last modified time", and the content of files on Dropbox. Under some conditions, the plugin would download the files. For example, the plugin would compare the last modified timestamps of the file in the local device and that on Dropbox, and if the timestamp on Dropbox is larger, the plugin would download the "newer" file from Dropbox to local.
+4. remotely-save uses "files.content.write", so that it can upload or overwrite the content of files on Dropbox. Under some conditions, the plugin would do that. For example, the plugin would compare the last modified timestamps of the file in the local device and that on Dropbox, and if the timestamp in the local device is larger, the plugin would upload the "newer" file from local to Dropbox, and overwrite that file on Dropbox.
+
+## Steps
+
+Here are the steps to see the functionality of remotely-save.
+
+Most steps have screenshots.
+
+1. Download the note-taking app Obsidian (Windows or Mac versions are both ok) from its official website: https://obsidian.md/ . It's free to download and use. Then install it.
+2. Open Obsidian, click the "Create" button under "Create new vault".
+3. Pick a vault name, "example-vault", and choose a location, then click "Create".
+   ![step03](./attachments/step03.png)
+4. Close any update new if prompted.
+5. Create a new note by clicking a button on the left. And write something on the note.
+   ![step05](./attachments/step05.png)
+6. Click "setting" (a gear icon) on the button left of the sidebar.
+   ![step06](./attachments/step06.png)
+7. In the settings panel, go to the "Community plugins" page, turn off the safe mode, and confirm to turn off the safe mode. Then click the "Browse" button for community plugins.
+   ![step07](./attachments/step07.png)
+8. Search "Remotely Save" and install on the result.
+   ![step08](./attachments/step08.png)
+9. After successful installing the plugin, go back to the "Community plugins" page, and enable the plugin.
+   ![step09](./attachments/step09.png)
+10. Go to newly added "Remotely Save" settings, select "Dropbox" in "Choose service", and click the "Auth" button.
+    ![step10](./attachments/step10.png)
+11. The standard auth flow address is shown, users should click the address, and finish the auth steps on the website. Finally, the Dropbox website should automatically redirect users back to the Obsidian app.
+    ![step11](./attachments/step11.png)
+12. The "Auth" button disappears. A new "Revoke Auth" appears.
+    ![step12](./attachments/step12.png)
+13. Go back to the main interface of Obsidian, a new "switch icon" should appear on the left sidebar. Click this, then the plugin would trigger the sync progress. It would compare meta info of local files and remote files (on Dropbox), and decide to download some files and/or upload some files.
+    ![step13](./attachments/step13.png)
+14. Create, edit, remove some notes, and repeat step 13, the files on Dropbox should also change to reflect the changes locally.

+# How To Debug
+
+Ideally, users do not need to debug anything. But if something bad happened, we have to dig into details.

+# Check Console Output
+
+If you are using Obsidian on desktop, you can check the Obsidian console.
+
+## Disable Auto Sync Firstly
+
+You should disable auto sync to avoid any unexpected running.
+
+## Set The Output Level To Debug
+
+Go to the plugin settings, scroll down to the section "Debug" -> "alter console log level", and change it from "info" to "debug".
+
+## Check The Output
+
+Then, press the keyboard shortcut "ctrl+shift+i" if you are on Windows or Linux, or press "cmd+shift+i" if you are on macOS. You should be able to see the console of Obsidian.
+
+Trigger the sync manually (by clicking the icon on the ribbon sidebar). Something (hopefully) helpful should show up in the console. You could understand what happened and what goes wrong more explictly by checking the output.

+# Export Sync Plans
+
+## What's this?
+
+Everytime the plugin starts a sync, it gathers all required information together, generates a "sync plan" of every operations to every files and folders, and assign the corresponding actual operations.
+
+Thus, if something goes wrong, we should check the sync plan firstly.
+
+## How To Export The Plans?
+
+Please read through the following instructions.
+
+### Disable Auto Sync Firstly
+
+You should disable auto sync to avoid any unexpected running.
+
+### Manual Sync If Not Yet
+
+You should at least sync once, so that at least one sync plan is generated and saved. If you have synced the vualt before, there should be some sync plans already saved.
+
+### Export To The File
+
+Go to the plugin settings, scroll down to the section "Debug" -> "export sync plans", and click the button "Export". \*\*It would generate a new folder `_debug_remotely_save/` in your vault, and generate a file `sync_plans_hist_exported_on_{a_timestamp},md.` inside that folder.
+
+## How To Read The Plans
+
+Open the genrated `sync_plans_hist_exported_on_{a_timestamp},md.`. You should see a json, or multiple jsons. Every json represents a sync plan.
+
+A sync plan looks like this:
+
+```json
+{
+  "ts": 1646960867560,
+  "remoteType": "onedrive",
+  "mixedStates": {
+    "abc.md": {
+      "key": "abc.md",
+      "existRemote": true,
+      "mtimeRemote": 1646566632000,
+      "sizeRemote": 56797,
+      "remoteEncryptedKey": "abc.md",
+      "changeMtimeUsingMapping": true,
+      "existLocal": true,
+      "mtimeLocal": 1646566632000,
+      "sizeLocal": 56797,
+      "decision": "skipUploading",
+      "decisionBranch": 1
+    },
+    "New folder/": {
+      "key": "New folder/",
+      "deltimeRemote": 1646925354372,
+      "existLocal": false,
+      "existRemote": false,
+      "decision": "keepRemoteDelHistFolder",
+      "decisionBranch": 9
+    }
+  }
+}
+```
+
+We usually care about the `mixedStates` property. As you may guess, every item in `mixedStates` represent a file or a folder.
+
+We should find out the file/folder we are interested in (or we believe something goes wrong), then checkout the following properties:
+
+```
+decision
+  What decision is made.
+
+decisionBranch
+  It's a mark of the actual logic in the sync code. Useful to debug.
+
+existRemote
+  Does the file/folder exist on the remote service?
+
+mtimeRemote
+  The "last modeified time" on the remote service.
+
+deltimeRemote
+  The "deletion time" on the remote record.
+
+existLocal
+  Does the file/folder exist locally?
+
+mtimeLocal
+  The max of "last modeified time" and "creation time" locally.
+
+deltimeLocal
+  The "deletion time" locally.
+```
+
+The `decision` SHOULD be determined by the modified times and deletion times, by the logic described in [the doc of sync alogorithm](../sync_algorithm_v2.md). In short, we collect four timestamps (`mtimeRemote`, `deltimeRemote`, `mtimeLocal`, `deltimeLocal`), and respect the max timestamp and its corresponding operation.
+
+## Common Issues
+
+Some users report that their "last modeified time"s or "creation time"s are not set correctly by the operating system. In this case, the plugin cannot do anything because it determines the sync plan by comparing the timestamps. It's suggested to check the settings of the operating system or check whether other programs are doing something to the files.

 # Minimal Intrusive Design
 
-The plugin tries to avoid saving additional meta data remotely.
+Before version 0.3.0, the plugin did not upload additional meta data to the remote.
+
+From and after version 0.3.0, the plugin just upload minimal extra necessary meta data to the remote.
 
 ## Benefits
 
-Then the plugin doesn't make any assumptions about information on the remote endpoint.
+Then the plugin doesn't make more-than-necessary assumptions about information on the remote endpoint.
 
 For example, it's possbile for a uses to manually upload a file to s3, and next time the plugin can download that file to the local device.
 
 And it's also possible to combine another "sync-to-s3" solution (like, another software) on desktops, and this plugin on mobile devices, together.
 
-## Flaws
+## Necessarity Of Uploading Extra Metadata
 
 The main issue comes from deletions (and renamings which is actually interpreted as "deletion-then-creation").
 
-Consider this:
+If we don't upload any extra info to the remote, there's usually no way for the second device to know what files / folders have been deleted on the first device.
 
-1. The user create and sync a file to the cloud on the 1st device.
-2. Then download this file to the 2nd device.
-3. And then delete this file on the 1st device.
-4. And sync on the 1st device. The file on the cloud is also deleted.
-5. And sync on the 2nd device. **The 2nd device would upload the file again to the cloud.**
-
-In step 4, the file is marked "deleted" on the 1st device, and the 1st device send the command "delete this file on the cloud" to the cloud sevice (e.g. s3). Then the file on the cloud is also deleted. So far so good.
-
-But, in step 5, because no meta data are saved on the cloud, the 2nd device doesn't know that the file are deleted. Instead, it thinks "the file was not synced to the cloud last time, so it's uploaded this time". So an unintentional upload occurs.
-
-Currently no way to fix this if no meta data are saved remotely. The only workarounds are:
-
-1. Delete the file on the 1st device, **before** syncing it to the cloud. Then the file never show up on the cloud or on the 2nd device.
-2. Or, manually delete the file on 2nd device **before** step 5 in above situation.
-
-## Future
-
-This design may be changed in the feature, considering the flaws described above.
+To overcome this issue, from and after version 0.3.0, the plugin uploads extra metadata files `_remotely-save-metadata-on-remote.{json,bin}` to users' configured cloud services. Those files contain some info about what has been deleted on the first device, so that the second device can read the list to apply the deletions to itself. Some other necessary meta info would also be written into the extra files.

+Here is an overview of the connectability ("connectable" or "not connectable" or "in the plan" or "never") to some services by this plugin.
+
+The plugin works under the browser environment in Obsidian, so CORS is an issue. Obsidian starts to provide a rich API `requestUrl` for desktop version >= 0.13.25, mobile >= 1.1.1 to bypass the CORS issue. But if the users are still using an older version of Obsidian, they need to configure CORS on server.

+2. Remote files. By scanning all files on the remote service. Some services provide an api directly returning this, and some other services require the plugin scanning the folders recursively.

+### Folders
+
+We actually do not use any folders' metadata. Thus the only relevent info is their names, while the mtime is actually ignorable.
+
+1. Firstly generate all the files' plan. If any files exist, then it's parent folders all should exist. If the should-exist folder doesn't exist locally, the local should create it recursively. If the should-exist folder doesn't exist remotely, the remote should create it recursively.
+2. Then, a folder is deletable, if and only if all the following conditions meet:
+
+   - it shows up in the remote deletion history
+   - it's empty, or all its sub-folders are deletable
+
+   Some examples:
+
+   - A user deletes the folder in device 1, then syncs from the device 1, then creates the same-name folder in device 2, then syncs from the device 2. The folder is deleted (again), on device 2.
+   - A user deletes the folder in device 1, then syncs from the device 1, then creates the same-name folder in device 2, **then create a new file inside it,** then syncs from the device 2. The folder is **kept** instead of deleted because of the new file, on device 2.
+   - A user deletes the folder in device 1, then syncs from the device 1, then do not touch the same-name folder in device 2, then syncs from the device 2. The folder and its untouched sub-files should be deleted on device 2.
