 # How to install this?
-I'd recommend using [flipperzero-ufbt](https://github.com/flipperdevices/flipperzero-ufbt), which is a lightweight tool for quickly testing Flipper Zero applications. The app will stay present on your device so it is not necessary to flash the entire firmware.
+
+The easiest way is to download the `counter.fap` file from `dist`, and place it inside of the `apps` folder on the SD card of your Flipper Zero device.
