<script src="/path/to/cornerstone.js"></script>

# NPM

npm install cornerstone-core --save

When used with a module system, you can import cornerstone like this:

You don't need to do this when using global script tags.

You will have to clone directly from GitHub and build cornerstone yourself if you want to use the latest dev build.

git clone https://github.com/cornerstonejs/cornerstone.git node_modules/cornerstone
cd node_modules/cornerstone
