+## Development Workflow
+
+- [VS Code prerequisites](https://github.com/Microsoft/vscode/wiki/How-to-Contribute#prerequisites)
+
+```shell
+yarn
+yarn vscode
+yarn watch # Visit http://localhost:8080 once completed.
+```
+
+Any changes made to the source will be live reloaded.
+
+If you run into issues about a different version of Node being used, try running
+`npm rebuild` in the VS Code directory.
+
+If changes are made to the patch and you've built previously you must manually
+reset VS Code then run `yarn vscode:patch`.
+
+Some docs are available at [../src/node/app](../src/node/app) on how code-server
+works internally.
+
+## Build
+
+- [VS Code prerequisites](https://github.com/Microsoft/vscode/wiki/How-to-Contribute#prerequisites)
+
+```shell
+yarn
+yarn build
+node build/out/entry.js # You can run the built JavaScript with Node.
+yarn binary             # Or you can package it into a binary.
