+You almost never need to update `create-guten-block` itself: it delegates all the setup to `cgb-scripts`. But as this project matures, there might be a few changes over time and you can re-run the global install.
+
+```js
+npm install create-guten-block --global
+```
 
 When you run `create-guten-block`, it always creates the project with the latest version of `cgb-scripts` so you’ll get all the new features and improvements in newly created plugins automatically.
