+Configuration of Semantic Release takes place in multiple places:
+
+* [`.releaserc.json`](.releaserc.json): Semantic Release is configured in this
+  file. For example the plugins used or plugin specific configuration. Currently
+  this project uses the Conventional Commits preset, a bunch of additonal types
+  and a few additional release rules.
+
+* [`.local/ci/`](.local/ci): Dependency management for the Semantic Release
+  environment. At runtime in CI/CD pipeline the `package.json` and lock file are
+  copied to the root of the project.
+
+* [`.github/workflows/primary.yaml`](.github/workflows/primary.yaml): Here Semantic
+  Release is actually executed.
