 I'm glad you asked!
 - If you want to clone a specific branch, simply use the `/` delimiter. To clone repository `foo` on branch `bar`, use `id:foo/bar`.
 - If you want a specific package to build first, use instances of `!` to set priority. This is explained later in the [Repository Mode](REPOSITORY_MODE.md) page
+- If you want to clone the repository with a specific depth, for example, in the case of a large git repository like `nixpkgs`, you can add a 2nd `:` delimiter and the integer after that will be used as the depth
 
 That's literally it!
