 ## Develop
 
+Source is CommonJS (`src/index.js`). The desktop loads `dist/index.js`.
+
+```
+npm run build   # copies src/index.js → dist/index.js
+npm run pack    # dripnex-plugin pack .
+```
+
+Same steps by hand:
+
 ```
-# edit src/index.js, then
 cp src/index.js dist/index.js
 dripnex-plugin pack .
 ```
 
 Attach `stamp-0.1.0.tar.gz` to the GitHub release for that tag.
+
+## Contribute
+
+Open a pull request. Keep the change small and focused on one fix or one small improvement.
+
+Edit `src/index.js`, then run `npm run build` so `dist/index.js` stays in sync.
