Audiolet comes with everything you need to get started, with the exception of a browser. Currently it supports Firefox 4 and versions of Chrome with the Web Audio API enabled.
To get started with Audiolet, clone the git repository and create a copy of the template in the examples folder. A recently compiled version of Audiolet is kept in the audiolet/ directory. You'll want to start a web server like live-server in the root directory of the Audiolet repository.
