 # Release `probod-bootstrap`
 
-Entrypoint for releasing `probod-bootstrap`. Read [README.md](./README.md)
-first for overall flow, changelog rules, and the non-empty-track
-guarantee.
+After confirming commits below, follow the
+[common steps](./README.md#3-common-steps-every-track).
 
 ## Track facts
 
 - **Tag pattern**: `probod-bootstrap/v*`
-- **Version source**: `cmd/probod-bootstrap/VERSION` (contains only `X.Y.Z`)
+- **Version source**: `cmd/probod-bootstrap/VERSION` (single `X.Y.Z` line)
+- **Version bump**: Edit `cmd/probod-bootstrap/VERSION` directly
 - **Changelog**: `cmd/probod-bootstrap/CHANGELOG.md`
+- **Files to stage**: `cmd/probod-bootstrap/VERSION`,
+  `cmd/probod-bootstrap/CHANGELOG.md`
 - **Workflow**: `.github/workflows/release-probod-bootstrap.yaml`
-- **Path filter** (for log/scoping): `cmd/probod-bootstrap`
+- **Path filter**: `cmd/probod-bootstrap`
 
-## Steps
+## Detect commits
 
-1. From a clean `main`, list commits since the last `probod-bootstrap`
-   tag:
+```shell
+git log $(git describe --tags --abbrev=0 --match='probod-bootstrap/v*')..HEAD --oneline \
+  -- cmd/probod-bootstrap
+```
 
-   ```shell
-   git log $(git describe --tags --abbrev=0 --match='probod-bootstrap/v*')..HEAD --oneline \
-     -- cmd/probod-bootstrap
-   ```
+If empty or non-user-facing only, do not release this track.
 
-   If the list is empty (or contains only non-user-facing commits), do
-   not release this track.
+## Notes
 
-2. Decide the version bump (PATCH for fixes, MINOR for features).
-3. Bump the version in `cmd/probod-bootstrap/VERSION`.
-4. Write the new entry in `cmd/probod-bootstrap/CHANGELOG.md` following
-   the rules in [README.md](./README.md#2-writing-a-changelog-entry).
-5. Show the user the changelog diff and the new version. Wait for
-   confirmation.
-6. Stage only `cmd/probod-bootstrap/VERSION` and
-   `cmd/probod-bootstrap/CHANGELOG.md`. Commit subject:
-   `Release probod-bootstrap/v<version>`. No body.
-7. Annotated tag:
-   `git tag -a probod-bootstrap/v<version> -m "probod-bootstrap/v<version>"`.
-8. Push: `git push origin main --follow-tags`.
-
-CI workflow `release-probod-bootstrap.yaml` builds binaries for 9 OS/arch
-targets and publishes a GitHub Release. Note: the same binary, built
-from the tagged ref, is also bundled into the probod Docker image when
-`probod/v*` runs.
