You need to have a working copy of Elm in your $PATH.
After that, you can make install to pull needed dependencies (for now, only OSX and Linux 64bit are supported).
Then you can run make to build the project. Everything will be bundled in the build directory, which can be served
by any static file server.
For development, make sure you have Watchman installed.
You can then run make watch to start watching files.
For convenience, make server will start a live-reload enabled server.
