The roadmap is entirely specified in the TODO file, which follows the git-done syntax. You can also use git done instead of git commit if you wish. For minor bug fixes, you won't need to deal with the TODO file. But if you're building a feature, remember to write a DONE entry before you commit and send the pull request.

The build system is using npm scripts. To develop, build the project with npm run build.

And access the site on your local machine as file:///path/to/rxmarblesrepo/index.html.

Make a pull request when you're ready.
