 The goal of this project is to build an Event Map that Warren supporters & volunteers can use to find events near their area!  It loads the events via the Mobilize API ([docs for /events endpoint](https://github.com/mobilizeamerica/api#request-2)).
 
+## Working version
+
+The event map is now live at [https://techforwarren.github.io/eventmap/](https://techforwarren.github.io/eventmap/)! Future merges to the `gh-pages` branch will update this site.
