+#### Android
+
+*Experimental* Code can be compiled and run on Android devices
+
+##### Environment setup
+
+* Install the [Termux](https://termux.com) app from FDroid or the Google Play store
+* Install a [PRoot](https://wiki.termux.com/wiki/PRoot) of your choice following the instructions for your preferred distribution.

+*Assuming Ubuntu PRoot is used*
+
+```bash
+# Install prerequisites
+apt install librocksdb-dev libpcre3-dev
+
+# Clone repo and build Nimbus just like above
+git clone https://github.com/status-im/nimbus.git
+
+cd nimbus
+
+make
+
+make nimbus
+
+build/nimbus
+```
