+#### Release, upload, and k8s deployment
+
+The release flow can be executed manually in three steps:
+
+```
+make release v1.2.3
+make upload TAG=v1.2.3
+make k8deploy TAG=v1.2.3 IMAGEBOT_URL=<imagebot-url>
+```
+
+`make release <tag>` calls `buildRelease.sh`, updates the changelog, creates
+the release commit and tag, and pushes them to the configured git remote.
+
+`make upload` builds the local `dbs2go` binary with Oracle support enabled by
+default, builds the Docker image, and pushes it to
+`registry.cern.ch/cmsweb/dbs2go`. Stable release tags also push a
+`<tag>-stable` image tag.
+
+`make k8deploy` runs the imagebot deployment step. The repository passed to
+imagebot is resolved from the `upstream` git remote, then `origin`, and finally
+falls back to `dmwm/dbs2go`. It can be overridden with `REPO=<owner>/<repo>`.
+
+For builds without Oracle drivers, use either form:
+
+```
+make upload no-oracle TAG=v1.2.3
+make upload-no-oracle TAG=v1.2.3
+```
+
+The k8s deployment target accepts the same suffix for command consistency,
+although it does not build anything after the upload/deploy split:
+
+```
+make k8deploy no-oracle TAG=v1.2.3 IMAGEBOT_URL=<imagebot-url>
+make k8deploy-no-oracle TAG=v1.2.3 IMAGEBOT_URL=<imagebot-url>
+```
