+
+## Scripts
+
+### `npm run dev`
+
+Runs the codeshift CLI useful for testing transform files as if they have been published
+
+**example:** `npm run dev -t src/10.0.0/transform.ts`
+
+See the [cli reference](https://www.codeshiftcommunity.com/docs/cli) for more information.
+
+### `npm run test`
+
+Launches the test runner in interactive watch mode.
+
+See the [testing guide](https://www.codeshiftcommunity.com/docs/testing) for more information.
+
+### `npm run validate`
+
+Checks the validity of your `codeshift.config.js` file.
+
+See the [configuration options](https://www.codeshiftcommunity.com/docs/configuration) for more information.
+
+### `npm run build`
+
+Builds the app for production to the `dist` folder.
+
+## Publishing
+
+This package can be published to npm via the normal commands `npm version` and `npm publish`
+
+## Build tooling
+
+Feel free to replace the preinstalled build tooling & dependencies to suit your needs. The only requirement is that there is a valid `codeshift.config.js` in your project root, `/src` or `/codemods` directories.
