+## Updating Go version
+
+When it is time to update the Go version in the project, you should make sure that the Go version is the same across the different tools in this repository.
+
+Most importantly, the Go version must be bumped in [Octo](octo/octo.go#L33) and in the [actions Dockerfile](actions/Dockerfile#L1) at the same time.
+
+The Go version is also in [the different workflows](.github/workflows), however, this will be updated automatically by `octo`. You can run `octo` locally or submit a PR, and when the PR is merged CI will run `octo` and in turn submit another PR that updates the Go version.
