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.

~~~ sh

$ npm install

$ npm run-script dist

$ MODULES="zepto event data" npm run-script dist

The resulting files are:

1. `dist/zepto.js`

2. `dist/zepto.min.js`

If you install CoffeeScript globally, you can run `make` directly:

~~~ sh

$ coffee make dist

$ MODULES="zepto event data ..." ./make dist

Zepto modules are individual files in the "src/" directory.

Zepto docs are written in Markdown and live in the ["gh-pages" branch][docs].

They are published on [zeptojs.com][].

You can use GitHub's web interface to make quick changes to documentation for

specific Zepto features

([example: ajaxSettings](https://github.com/madrobby/zepto/blob/gh-pages/ajax/_posts/1900-01-01-Z-ajaxSettings.md)).

This will submit a pull request to us that we can review.

1. Check if the bug is already fixed in the [master branch][master] since the

last release.

2. Check [existing issues][issues]. Open a new one, including exact browser &

platform information. For better formatting of your report, see

[GitHub-flavored Markdown][mkd].

You will need to install [PhantomJS][]. On OS X, that's easy:

~~~ sh

$ brew install phantomjs

To run the automated tests:

~~~ sh

$ npm test

To run a test server, which you can hit with your browsers and devices:

~~~ sh

$ npm start

Go 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).
