Zepto is a minimalist JavaScript library for modern browsers with a largely jQuery-compatible API. If you use jQuery, you already know how to use Zepto.
See zeptojs.com for an extended introduction, downloads and documentation.

The official site offers a download of the default distribution of Zepto. This is good for starting out. However, at some point you might want to add some optional modules and remove some of the default ones you don't need, to keep the size at a minimum. That's when you need to check out Zepto's source code and use the build commands.
You will need Node.js installed on your system.
$ npm install
$ npm run-script dist
# do a custom build
$ MODULES="zepto event data" npm run-script distThe resulting files are:
dist/zepto.jsdist/zepto.min.js
If you install CoffeeScript globally, you can run make directly:
$ coffee make dist
$ MODULES="zepto event data ..." ./make distZepto modules are individual files in the "src/" directory.

You will need to install PhantomJS. On OS X, that's easy:
$ brew install phantomjsTo run the automated tests:
$ npm testTo run a test server, which you can hit with your browsers and devices:
$ npm startGo to http://your-ip-address:3000/ on your browser and follow the
instructions. For your convenience test failures and exceptions will be
reported to the the console you started the test server in (as well as
the browser console if available).
