 ### Manual installation
 
 - Download and unzip `uMatrix.chromium-{version}.zip` ([latest release desirable](https://github.com/gorhill/uMatrix/releases)).
-- Rename the unzipped directory to `uMatrix.chromium`
+- Rename the unzipped directory to `uMatrix.chromium` (if it is different)
     - When you later update manually, replace the **content** of the `uMatrix.chromium` folder with the **content** of the latest zipped version.
     - This will ensure that all the extension settings will be preserved
     - As long as the extension loads **from same folder path from which it was originally installed**, all your settings will be preserved.
