 event-tracking
 ==============
 
-@@@
+This is a system for tracking events.  It is designed to support pluggable
+backends for persisting the event data. When the application emits an event
+each backend will be given an opportunity to save the event to stable storage.
+
+Roadmap
+-------
+
+In the very near future the following features are planned:
+* Layered contexts - allowing data to be injected into events even without
+    having to pass around all of said data to every location where the events
+    are emitted.
+* Django integration - provide a Django app that allows events to easily be
+    captured by web applications.
+* Dynamic documentation and event metadata - allow event emitters to document
+    the event types, and persist this documentation along with the events so
+    that it can be referenced during analysis to provide context about what
+    the event is and when it is emitted.
