+P.S. Don't miss the game over screen.
+
+## Installing the binary file (no build needed)
+
+Drop the `asteroids.fap` file you can find in the `binaries` folder into the
+following Flipper Zero location:
+
+    /ext/apps/Tools
+
+The `ext` part means that we are in the SD card. So if you don't want
+to use the Android (or other) application to upload the file,
+you can just take out the SD card, insert it in your computer,
+copy the fine into `apps/Tools`, and that's it.
+
+## Installing the app from source
+
+* Download the Flipper Zero dev kit and build it:
+```
+mkdir -p ~/flipperZero/official/
+cd ~/flipperZero/official/
+git clone --recursive  https://github.com/flipperdevices/flipperzero-firmware.git  ./
+./fbt
+```
+* Copy this application folder in `official/application_user`.
+* Connect your Flipper via USB.
+* Build and install with: `./fbt launch_app APPSRC=asteroids`.
