+# About the Agaric Pattern Library & Style Guide
+
+This living styleguide is powered by the same styles as power the Agaric site itself.  Changes in `agaric/sass/agaric/` will be reflected both in the styleguide and ultimately on the live sites, so be cautious!
+
+## Set up
+
+#### Use the right version of node with:
+`nvm use`
+
+_This command will look at your `.nvmrc` file and use the version node.js specified in it. This ensures all developers use the same version of node for consistency._
+
+#### If that version of node isn't installed, install it with:
+`nvm install`
+
+#### Install npm dependencies with
+`npm install`
+
+_This command looks at `package.json` and installs all the npm dependencies specified in it.  Some of the dependencies include grunt and grunt-sass._
+
+## Usage
+
+### Compile CSS
+
+`grunt sass`
+
+See more available Grunt commands:
+
+`grunt --help`
+
+
+## Stuff we're not using
+
+### Rebuild the style guide
+
+`grunt kss`
+
+### Run the static design layouts
+
+`grunt`
+
+_This will open the static layouts in your browser.  At the bottom you can click between them and to the style guide._
+
+## Contents
+
+The `agaric` folder contains the styles, as Sass .scss files, that we expect to be applicable to all Agaric-branded web applications.
+
+### Markup examples and static layouts
+
+See `styleguide/index.html` for project info.
