 `npm rebuild` in the VS Code directory.
 
-### Upgrading VS Code
-
-We patch VS Code to provide and fix some functionality. As the web portion of VS
-Code matures, we'll be able to shrink and maybe even entirely eliminate our
-patch. In the meantime, however, upgrading the VS Code version requires ensuring
-that the patch still applies and has the intended effects.
-
-To generate a new patch, **stage all the changes** you want to be included in
-the patch in the VS Code source, then run `yarn patch:generate` in this

-
-Our changes include:
-
-- Allow multiple extension directories (both user and built-in).
-- Modify the loader, websocket, webview, service worker, and asset requests to
-  use the URL of the page as a base (and TLS if necessary for the websocket).
-- Send client-side telemetry through the server.
-- Make changing the display language work.
-- Make it possible for us to load code on the client.
-- Make extensions work in the browser.
-- Fix getting permanently disconnected when you sleep or hibernate for a while.
-- Make it possible to automatically update the binary.

+Implementation of [VS Code](https://code.visualstudio.com/) remote/web for use
+in `code-server`.
+
+## Docker
+
+To debug Golang in VS Code using the
+[ms-vscode-go extension](https://marketplace.visualstudio.com/items?itemName=ms-vscode.Go),
+you need to add `--security-opt seccomp=unconfined` to your `docker run`
+arguments when launching code-server with Docker. See
+[#725](https://github.com/cdr/code-server/issues/725) for details.
+
+## Known Issues
+
+- Creating custom VS Code extensions and debugging them doesn't work.
+- Extension profiling and tips are currently disabled.
+
+## Extensions
+
+`code-server` does not provide access to the official
+[Visual Studio Marketplace](https://marketplace.visualstudio.com/vscode). Instead,
+Coder has created a custom extension marketplace that we manage for open-source
+extensions. If you want to use an extension with code-server that we do not have
+in our marketplace please look for a release in the extension’s repository,
+contact us to see if we have one in the works or, if you build an extension
+locally from open source, you can copy it to the `extensions` folder. If you
+build one locally from open-source please contribute it to the project and let
+us know so we can give you props! If you have your own custom marketplace, it is
+possible to point code-server to it by setting the `SERVICE_URL` and `ITEM_URL`
+environment variables.
+
+## Development: upgrading VS Code
+
+We patch VS Code to provide and fix some functionality. As the web portion of VS
+Code matures, we'll be able to shrink and maybe even entirely eliminate our
+patch. In the meantime, however, upgrading the VS Code version requires ensuring
+that the patch still applies and has the intended effects.
+
+If functionality doesn't depend on code from VS Code then it should be moved
+into code-server otherwise it should be in the patch.
+
+To generate a new patch, **stage all the changes** you want to be included in
+the patch in the VS Code source, then run `yarn patch:generate` in this
+directory.
+
+Our changes include:
+
+- Allow multiple extension directories (both user and built-in).
+- Modify the loader, websocket, webview, service worker, and asset requests to
+  use the URL of the page as a base (and TLS if necessary for the websocket).
+- Send client-side telemetry through the server.
+- Make changing the display language work.
+- Make it possible for us to load code on the client.
+- Make extensions work in the browser.
+- Fix getting permanently disconnected when you sleep or hibernate for a while.
+- Make it possible to automatically update the binary.
+
+## Future
+
+- Run VS Code unit tests against our builds to ensure features work as expected.
