Try to use the project, break things, and open issues on Github.
Also, If you have ideas for Meuse, feel free to open issues ;)
You can open pull request on the Github project.
Meuse is written in Clojure. I use the Mount library for my reloaded workflow, you can start or stop the application from the REPL by using the user namespace in dev/user.clj.
You can launch the tests with lein test, and the integration tests with lein test :integration. You will need a running PostgreSQL database for the tests (you can launch it using Docker with the postgres.sh script).
