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
