+**A note about `pre-commit autoupdate`:**
+
+`pre-commit autoupdate` updates the `rev` for each repository defined in your `.pre-commit-config.yaml`
+to the latest available tag in the default branch.
+
+Poetry follows a branching strategy, where the default branch is the active developement branch
+and fixes gets back ported to stable branches. New tags are assigned in these stable branches.
+
+`pre-commit` does not support such a branching strategy and has decided to not implement
+an option, either on the [user side](https://github.com/pre-commit/pre-commit/issues/2512)
+or [hook author side](https://github.com/pre-commit/pre-commit/issues/2508), to define a branch for lookup the latest
+available tag.
+
+Thus, `pre-commit autoupdate` is not usable for the hooks described here.
+
+You can avoid changing the `rev` to an unexpected value, by using the `--repo` parameter (may be specified multiple
+times), to explicit list repositories that should be updated. An option to explicit exclude
+repositories [will not be implemented](https://github.com/pre-commit/pre-commit/issues/1959).
