+# Abit
+
+A Bitmessage client for Android.
+
+**Please be aware that due to the protocol, sending messages might suck your
+battery dry. Also, it causes a lot of traffic and may use up your data plan
+rather quickly. Use at your own peril.**
+
+Abit uses the [Jabit Bitmessage library](https://github.com/Dissem/Jabit).
+
+## Requirements
+You'll need at least Android 4.4 KitKat. Due to the Proof of Work that comes
+with the protocol you might want as fast a processor and as many cores as
+you can get.
