+Version Control
+==========
+
+A repository is represented in Bonsai by the [`CreateRepository`](xref:AllenNeuralDynamics.VersionControl.CreateRepository) operator. Several properties are exposed via this object, including the name and hash of the current commit.
+
+In order to make it easier for users to evaluate the state of the local repository, an additional operator, [`IsRepositoryClean`](xref:AllenNeuralDynamics.VersionControl.IsRepositoryClean), is provided to check if the repository is in a clean state (i.e. are there any untracked or uncommitted changes).
