README file needs more info?

[hotternative]

I am beginner level developer. This looks like a useful work however the README file is a bit too concise for me to follow. I guess there are other people with a similar interest but face similar problem.

Could you briefly explain when to use mvn clean install
and when to use the following instead?
docker run -it --rm --name my-maven-project -v "$PWD":/usr/src/mymaven -w /usr/src/mymaven -v /var/run/:/var/run/ maven mvn clean install

Could you briefly explain what to do after cloning the repo to local PC?
Many thanks.

If you use mvn clean install, you need to install Maven and JDK in advance, and you also need to set the PATH. Please see Maven's official page for details.
