+# Releases
+
+## DEB packages
+
+Building DEB packages is tested on every CI run.
+This way developers can be sure that their code can be built to a package
+before they merge it.
+
+To make a DEB release:
+
+1.  Update the version in the `VERSION` file, for example, `v0.42.0`.
+2.  Push this commit to the `master` branch.
+3.  Push a tag on this commit, named same as the version:
+
+    ```
+    git tag v0.42.0
+    git push origin v0.42.0
+    ```
+
+4.  Wait for CI to build and publish the package.
