New contributor help wanted regarding setting up

Hi Team,
I am very new to Metabase community, I am very much interested in contributing to the Metabase community because of I really want to learn Clojure and I found there are ample issues in issues section of the GitHub of Metabase.
But before contributing to Metabase I want to use the tool so is there a way that I can get some dummy data and setup Metabase and run some operations on mock data?

Download the opensource edition. Download JDK 11.
Then it's just java -jar metabase.jar.
