+# Contributing
+
+Thanks for your interest in contributing!
+
+## Prerequisites
+
+- [Node.js](https://nodejs.org/) — version pinned in [`.node-version`](./.node-version).
+  Tools like [`nvm`](https://github.com/nvm-sh/nvm), [`fnm`](https://github.com/Schniz/fnm),
+  [`asdf`](https://asdf-vm.com/), or [`mise`](https://mise.jdx.dev/) read this file
+  automatically.
+- [`cosign`](https://docs.sigstore.dev/cosign/installation/) — only required if you
+  want to run the signature-verification integration tests locally.
+
+## Setup
+
+```sh
+npm ci
+```
+
+## Pre-commit checklist
+
+Before committing changes to `src/`, `__tests__/`, `package.json`,
+`package-lock.json`, or `action.yml`:
+
+```sh
+npm run pre-checkin
+```
+
+That runs `format` + `build` + `test` — the same checks CI runs.
+
+Then commit `dist/` along with your source changes; the action runtime loads
+`dist/index.js` directly, so it must stay in sync.
+
+If CI's `validate / build` job fails because `dist/` differs from a fresh
+build, just download the `dist` artifact from the failed run and commit it —
+or rerun `npm run build` locally with the Node version in `.node-version`.
+
+## npm scripts
+
+| Script              | Purpose                                          |
+| ------------------- | ------------------------------------------------ |
+| `npm run build`     | Bundle `src/` to `dist/index.js` via `ncc`       |
+| `npm run format`    | Run Prettier (write)                             |
+| `npm run format-check` | Run Prettier (check only, used in CI)         |
+| `npm run lint`      | Run ESLint (check only, used in CI)              |
+| `npm run lint:fix`  | Run ESLint with `--fix`                          |
+| `npm test`          | Run Jest with coverage                           |
+| `npm run pre-checkin` | `format` + `lint:fix` + `build` + `test`       |
+
+## Tests
+
+`npm test` runs the full Jest suite, including integration tests that:
+
+- Download real GoReleaser releases from GitHub
+- Verify `checksums.txt` against the downloaded archive
+- Verify the cosign sigstore bundle (skipped if `cosign` isn't on `PATH`,
+  but the CI image always has it installed)
+
+These need outbound network access. Offline / restrictive-proxy runs will
+have those tests fail — that's expected.
+
+## Commit messages
+
+Use [Conventional Commits](https://www.conventionalcommits.org/) (`feat:`,
+`fix:`, `test:`, `docs:`, `chore:`, `ci:`, …). Keep the subject ≤72 chars.
+
+## Pull requests
+
+- Target `master`.
+- Make sure `npm run pre-checkin` passes.
+- One logical change per PR is easier to review.
+- The `signing` CI job and `goreleaser-pro` matrix entries are skipped on PRs
+  from forks because they need repository secrets — that's expected and not
+  something you need to fix.
+
+## Releasing (maintainers)
+
+1. Create a new GitHub Release with a semver tag (e.g. `v7.1.0`) — either
+   through the UI or `gh release create v7.1.0 --generate-notes`.
+2. Once the release exists, run the [**release major tag**](./.github/workflows/release-major-tag.yml)
+   workflow from the Actions tab:
+   - `target`: the new tag (e.g. `v7.1.0`)
+   - `major_version`: the major version to repoint (e.g. `v7`)
+
+   This force-pushes the major tag to the new release so consumers using
+   `goreleaser/goreleaser-action@v7` pick up the change.
+
+   The same workflow doubles as a rollback tool — pass an older tag as
+   `target` to revert the major.

+### Verification
+
+The action verifies the integrity of the downloaded GoReleaser archive
+against the published `checksums.txt` automatically — no configuration
+required.
+
+If [`cosign`](https://docs.sigstore.dev/cosign/) is available on `PATH`, the
+action will additionally verify the cosign sigstore signature of the
+checksums file against the GoReleaser release workflow's OIDC identity. If
+`cosign` isn't installed, this step is silently skipped.
+
+> **Note**: cosign signature verification requires GoReleaser **v2.13.0 or
+> newer** (and the matching `nightly`). Earlier releases ship a `.sig`
+> detached signature signed with cosign v2, which is not compatible with
+> the cosign v3 sigstore-bundle format the action verifies. For older
+> versions the cosign step is silently skipped — only the `checksums.txt`
+> SHA-256 verification runs.
+
+> **Note**: when `version: nightly` is used, the action resolves the
+> latest immutable `vX.Y.Z-<sha>-nightly` release from the GitHub
+> Releases API. Pass `GITHUB_TOKEN` to the action step (as in the example
+> above) to avoid unauthenticated API rate limits.
+
+To enable signature verification, install cosign before running the action:
+
+```yaml
+      -
+        name: Install cosign
+        uses: sigstore/cosign-installer@v3
+      -
+        name: Run GoReleaser

+          args: release --clean
+        env:
+          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
+```
+
+Both checksum and signature verification work for tagged releases (≥ v2.13.0)
+and the `nightly` channel.
