 Note: by default standard will look for all files matching the patterns: `"**/*.js"`, `"**/*.jsx"`. Always quote the globs. Needed when used as an `npm` command.
 
+### `prepublish`
+
+Transpile a library using [Babel](http://babeljs.io/) and our custom config. Usually used as a prepublish step for libraries written in ES6+ that will be published to NPM. Pass it a directory and it will look for `.js` files to transpile.
+
+```shell
+$ mastarm prepublish lib:build
+```
+
 ### `test`
 
 Run the [Jest](http://facebook.github.io/jest/) test runner on your project. By default, mastarm will run Jest and generate coverage reports on all .js files in the `lib` folder of your project. The `patterns` argument will make Jest run only tests whose filename match the provided pattern.
