+
+You can install and update QodeAssist directly from within Qt Creator by adding the QodeAssist registry as an external extension repository.
+
+1. Open the Extensions page (`Qt Creator → Extensions`) and switch to the **Browser** tab
+2. Enable **Use External Repository**
+3. Next to **Repository URLs**, click **Add** and paste the registry archive URL matching your Qt Creator version:
