+### `nodecg-io generate`
+
+Generates a new bundle in the `bundles/` directory in your nodecg installation.
+Allows you to decide on language (typescript or javascript), whether you want a dashboard/graphic and which services you want to use.
+Uses your installed nodecg-io version and services, meaning you need to have the services that you want to use installed.
+
+These generated bundles are only meant as a starting point, you may probably do more things like creating a git repository for your bundle,
+add a license, or add other tools like linters.
+
+Also this command currently only works with installs of released versions and not with development installs. This is because all bundles using nodecg-io depend on `nodecg-io-core` and if you use typescript each used service as well. For development installs these are not published on npm and you would need some way of linking the packages locally.

 ## A note about versioning
 
 This cli follows and is versioned independently from the rest of nodecg-io like `nodecg-io-core` or the services.
