-Here is a sample Dockerfile to get you started.
+The project has
+[docker image](https://hub.docker.com/repository/docker/retropikzel1/compile-r7rs/general).

+It is statically built with Chicken scheme and installed under /opt/compile-r7rs,
+so it can be copied in your Dockerfile.

 To use this run:
 
-    export COMPILE_R7RS=<your scheme>
-    docker build --build-arg COMPILE_R7RS=${COMPILE_R7RS} --tag=compile-r7rs-${COMPILE_R7RS} .
-    docker run -v "${PWD}":/workdir -w /workdir -t compile-r7rs-${COMPILE_R7RS} sh -c "compile-r7rs -I -o main ./snow main.scm"
