   * ### How do I install a specific version of vDSM?
 
     By default, version 7.2 will be installed, but if you prefer an older version, you can add its URL to your compose file as follows:
 
     ```yaml
     environment:
-        URL: "https://global.synologydownload.com/download/DSM/release/7.1.1/42962-1/DSM_VirtualDSM_42962.pat"
+        URL: "https://global.synologydownload.com/download/DSM/release/7.0.1/42218/DSM_VirtualDSM_42218.pat"
     ```
 
     With this method, you are able to switch between different versions while keeping your file data.
