+
+This repository contains the code for an Android Bitcoin Wallet powered by [Floresta](https://github.com/vinteumorg/floresta). It currently works 
+only on [signet](https://en.bitcoin.it/wiki/Signet), you can try to get some coins to test [here](https://signetfaucet.com/)
+
+## Architecture
+
+To make this work, florestad is spawned as a foreground service, that keeps running on the background. When you need to access it, the wallet 
+uses either the RPC or Electrum Protocol to request data. By doing so, we can have all the Bitcoin-related functionality inside a single 
+application, without requiring additional steps from the user.

+
+## Building
+
+The easiest way to build this project is through [Android Studio](https://developer.android.com/studio). Inside it you can build and export the 
+native APK to your devices. We currently support armv8 and x86_64. The minimum API level is 27.
