+## Building using the Dockerfile
+
+It's possible to use a docker image for building. This way you don't need anything installed on your host system.
+
+```
+# Build docker image (only needed once)
+docker build . -t jstypehax-payload-builder
+
+# make 
+docker run -it --rm -v ${PWD}:/project jstypehax-payload-builder make
+
+# make clean
+docker run -it --rm -v ${PWD}:/project jstypehax-payload-builder make clean
