+# Dockerfile for github.com/jeelabs/esp-link

+# This dockerfile is intended to be used to compile esp-link as it's checked out on
+# your desktop/laptop. You can git clone esp-link, and then compile it using
+# a commandline of `docker run -v $PWD:/esp-link jeelabs/esp-link`. The -v mounts
+# your esp-link source directory onto /esp-link in the container and the default command is
+# to run make.
+# If you would like to create your own container image, use `docker build -t esp-link .`
+FROM ubuntu:16.04
