Improve Documentation; Add CI Examples

[naftulikay]

@ilianaw Would you like to keep this paragraph in the README and this builder/ project in the repository?

The builder directory of the crowbar git repo contains a Dockerfile with Rust set up and a build script to dump a zip file containing a stripped shared library to stdout. Documentation for using that is available at ilianaw/crowbar-builder on Docker Hub.

The examples and documentation that I have provided in this PR kind of defeat the usefulness of the builder/ directory.

_{i lost so much time to this :disappointed:}
