+# Story Tracer
+
+Story Tracer is a Chrome extension that identifies the source information that web pages are based upon. Story Tracer uses the [ground-truth](https://github.com/ReportersLabDuke/ground-truth) node library.
+
+## How it works
+
+When you navigate to a webpage with Story Tracer added to Chrome, Story Tracer will try to identify the source behind the webpage by looking at the links on the page. If a likely source is identified, a popup will appear indicating that the page you are on might be based on content from another page:

+## Installation instructions
+
+Story Tracer is not yet available on the Chrome webstore. This repository can be downloaded and then added to Chrome as an extension in developer mode.
