+## The goal of this file, is to provide an easy and reproducible way to check *locally*
+## the CI job `docker-alpine-musl-gcc`
+## Building the docker image:
+##    docker build -t ci_alpine_local - < .github/workflows/Dockerfile.ci_alpine_local
+## Running the docker image, after building it:
+##    docker run --rm -it -v .:/opt/vlang -w /opt/vlang ci_alpine_local
+## Once it is running, inside the container you can:
+##    make && v -e 'println(2+2)'
+## ... then do whatever you need to reproduce the CI test failure.
+## Note: after you are finished, and exit the container, run `make` again, otherwise 
+## you will be using V (and potentially V tools) that were compiled with musl.
