##Installation

In Node.js:

npm install turf

In browser:

Download the minified file, and include it in a script tag. This will expose a global variable named "turf".

<script src="turf.min.js" charset="utf-8"></script>

Browserify:

All of Turf's functions can also be installed as seperate modules. This works well with tools like browserify where you only want to install only the code you need. It also allows you to mix and match modules as needed. This is the recommended usage pattern for most production environments. For example, to install the point and buffer modules use:

npm install turf-point
npm install turf-buffer
