+## 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.

+# 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.

 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 version >= 0.13.25 to bypass the CORS issue. But if the users are still using an older version of Obsidian, they need to configure CORS on server.
