## Overview

Files in the `source` directory are resources for deployment to the CDN.

Files in the `website` directory are specific to the website.

`config.json` is used to control building, staging, and deployment


## Deploying to the CDN

To stage your changes to a versioned directory in your local CDN repository, type `fab stage` This runs a build, copies the files into a versioned directory in your local `cdn.knightlab.com` repository, and tags the last commit with a version number.

To stage your changes to the `latest` directory in your local CDN repository, type `fab stage_latest` This copies files from a versioned directory in your local `cdn.knightlab.com` respository into the corresponding `latest` directory. 

You must push and deploy all CDN changes separately from that repository.


## Deploying to S3 (timeline.knightlab.com)

To deploy to S3, type `fab deploy`.
