# This CI is disabled on main and meant to be enabled on forks as an easy way to cherry pick fork commits into main.
# In order to submit a PR from your repo to the Cosmos SDK, a PRBOT_PAT secret (personal access token) must be available for the GitHub Action (Settings > Secrets > Actions).
# The PR will be submitted from the user of the PAT. Note, the PRBOT_PAT user must have write access to the repo.
