+## Milestones
+
+To associate one or more milestones with a GitLab release, set the `gitlab.milestones` option to an array of the
+titles of the corresponding milestones, for example:
+
+```json
+{
+  "gitlab": {
+    "release": true,
+    "milestones": ["${version}"]
+  }
+}
+```
+
+Note that creating a GitLab release will fail if one of the given milestones does not exist. release-it will check this
+before doing the release. To skip this check, use `gitlab.skipChecks`.
