+## Versioning and releasing
+
+We use semantic versioning: `v{major}.{minor}.{patch}`, e.g. `v0.1.0`.
+
+Merging a pull request will generate a new **minor** version, and a **tag** will be automatically created in the repository.
+
+Next, an image will be built and pushed to the Docker repository with the new version.
