# This workflow runs when PRs labeled `major`, `minor`, or `patch` are closed | |
# and increments version numbers. Then, it opens a PR labeled `release` for the | |
# changes. When that PR is merged, a release is created (see `release.yaml`). | |
# | |
# Are you here because I left Mercury and now my personal access token is | |
# invalid for workflows, breaking CI? You'll want to go to | |
# https://github.com/MercuryTechnologies/nix-your-shell/settings/secrets/actions | |
# and update the `REPO_GITHUB_TOKEN` secret to a new, valid token. | |
