-While in pre-release, you will need to side-load the extension. You need to have the Windows 10 Anniversary Update to use extensions in Edge.

-1. Download the latest release from [the Releases page](https://github.com/nikrolls/uBlock-Edge/releases)

-3. Browse to `about:flags` in Edge and turn on the option `Enable extension developer features`
-4. Restart your browser
-5. Go to Extensions in the browser menu and click `Load extension`
-6. Select the `uBlock0.edge` folder you extracted earlier
