Build instructions are still up in the air at the moment. These docs will be updated when the correct build tool has been found.
To test in the browser, just open the test/index.html in a browser.
Testing in Node.JS can be done by first running npm install, followed by a
npm test.
If you want to test in a headless browser, first install phantomjs, and run
the tests with phantomjs test/phantom-js-loader.js.
If you want to develop Tempus, best place is to start off with the developer preface, which tells you everything you need. The most important thing is to ALWAYS submit tests with your code.
If you want to work on the Website itself, then please go over to the tempus-js.com git repository.
