+Title: Label
+---
+
+When first setting up a repository, it is nice to be able to configure a set of
+default labels, so that you can have some consistency across your various
+projects.  While GitHub, and other Source Control systems provide a set of
+default labels, they are not always exactly what you want.  This command will
+remove all the current labels configured within a repository, and create a new
+set of them.
+
+:::{.alert .alert-info}
+**NOTE:**
+
+The available list of labels that are created is currently hard-coded into
+GitReleaseManager, it is not possible to configure them.  This will come in a
+later version.
+:::
