 ## Release app installation
 
-Currently we are working on proper DMG signing on MacOS, in the mean time you can install existing [release build](https://github.com/DrewPackages/localhost/releases/tag/release1) using a workaround described in the top-rated answer [here](https://discussions.apple.com/thread/253714860?answerId=257037956022&sortBy=rank#257037956022)
+ You can find the latest app builds on the [releases page](https://github.com/DrewPackages/localhost/releases). Currently supported architectures:
+
+* **Windows** - DrewLocalhost-1.2.8.Setup.exe
+* **MacOS Intel** - Drew.Localhost.x64.dmg
+* **MacOS M-processors (arm)**
+  * Best option is to still download **Drew.Localhost.x64.dmg** executable since it can be run the same as any non-app-store app, [see here](https://support.apple.com/guide/mac-help/open-a-mac-app-from-an-unknown-developer-mh40616/mac)
+
+  * If you download **Drew.Localhost.arm64.dmg** executable - you need to follow the instructions [described here](https://discussions.apple.com/thread/253714860?answerId=257037956022&sortBy=rank#257037956022), in short - copy Drew Localhost app normally to Applications folder and run this command in terminal:
+ ```
+ xattr -c /Applications/DrewLocalhost.app
+ ```
+
+ Currently we are working on proper DMG signing on MacOS (and possibly - distribution through App Store), in the mean time follow the instructions above, or build the app yourself
