+  - repo: https://github.com/vektra/mockery
+    rev: v2 # This is a mutable reference to the latest version
+    hooks:
+      - id: generate-mocks

+
+!!! note
+
+    If the file is missing, you can simply create it with this content
+
+Then install the hook with the following command:
+
+```console
+# This one will report a warning about mutable reference
+$ pre-commit install
+
+# This one will fix the warning
+$ pre-commit autoupdate
+```

+It will install everything. And from now, your commit will trigger mock generation.
