+      description: |-
+        Publishes a draft release and transitions it through the required review process. This allows Marketplace component publishers to manually publish a release that was created with the `publishManually` flag set to `true`.
+
+        **Authorization:** The user must have access to manage the component. The user is a developer of the component and meets user group rules.
+
+        **Prerequisites:**
+        - The release must exist in Marketplace.
+        - The release must be in `Draft` state.
+        - A source file must have been uploaded for the release.
+
+        **State Transition:**
+        After a successful publish request, the release transitions to one of the following states:
+        - `InReview`
+          - Mendix Admin approval is required for private components
+          - A security scan is required for public components
+        - `Published`
+          - Mendix Admin approval is not required for private components
+          - A security scan is not required
+
+        A release in the `InReview` state is automatically published to Marketplace and transitions to `Published` once all required review conditions have been satisfied.
+
+        **Response:** Use GET /releases/{releaseId} to check the current status of the release.
