+## Development
+
+To run the extension locally:
+
+- copy environmental variables from `/web-app/.env.example` as `/web-app/.env`
+- install dependencies with `yarn install-all`
+- build the extension with `yarn build`
+- open the extension with the vscode extension debugger by pressing F5. In the new window, open CodeRoad.
+
+To test a packaged build locally:
+
+- if on Mac, ensure you have [VSCode command line tools](https://code.visualstudio.com/docs/setup/mac#_launching-from-the-command-line) installed
+- run `yarn package`. It will build the extension and install it locally.
+- open a new vscode window and launch the new version of CodeRoad
