+# @github1s/vscode-web
+
+This is the companion NPM package to support GitHub1s. The NPM package is [@github1s/vscode-web](https://www.npmjs.com/package/@github1s/vscode-web).
+
+## Commands
+
+`yarn clone` - clone the official VS Code repo.
+
+`yarn build` - build the VS Code with the custom code under `src`.
+
+`yarn watch` - watch the code change under `src` directory and rebuild VS Code.
+
+## Local development
+
+There are two ways to do local development with GitHub1s. For feature development, you could use the `yarn watch-with-vscode` under the root directory.
+
+To verify the NPM package content itself before publish. You need to install the [yalc](https://github.com/wclr/yalc) first (`yarn global add yalc`).
+
+Then run the following commands:
+
+```sh
+cd github1s
+yarn build:vscode # Build the VS Code
+yarn yalc # Install local package via yalc
+
+yarn build # Build the GitHub1s & other extensions
+yarn serve
+```
+
+And visit the http://localhost:5000 to verify the change. Please revert any changes related to `yalc` before commit, i.e. the `package.json`, the `.yalc/` and `yalc.lock` files.
+
+## Publish
+
+To publish the NPM package, please make sure you have the right access via https://www.npmjs.com/ and run the following commands:
+
+```sh
+cd github1s
+cd vscode-web-github1s
+yarn build
+# bump the `version` field in vscode-web-github1s/package.json file.
+npm publish --access public
+```
