+Initial setup
+=============
+Building packages are for now only tested to work on Ubuntu 15.04. Perform the following
+setup steps:
+
+* Run `ubuntu-setup.sh` to install required packages and setup the `/data/` folder (see below).
+
+* Install the Android SDK at `$HOME/lib/android-sdk`. Override this by setting the environment
+variable `$ANDROID_HOME` to point at another location.
+
+* Install the Android NDK, version r10e, at `$HOME/lib/android-ndk`. Override this by setting
+the environment variable `$NDK` to point at another location.
+
+Alternatively a Dockerfile is provided which sets up a pristine image
+suitable for building packages. To build the docker image, run the
+following command:
+
+ docker build --rm=true -t termux .
+
+After build is successful, you can open an interactive prompt inside the
+container using:
+
+ docker run --rm=true -ti termux /bin/bash
