-Please only modify `js/jquery.terminal-src.js`/`css/jquery.terminal-src.css` files. You can run `make` but you may have conflicts. Other contributors push commits with their builds (you may have conflicts because there is a build date and time in the build file). Make sure you're on the devel branch, and create a PR to the devel branch as well.
