+Packaging [Isotope](http://isotope.metafizzy.co/) for [Meteor.js](http://meteor.com).
+
+
+# Meteor
+
+If you're new to Meteor, here's what the excitement is all about -
+[watch the first two minutes](https://www.youtube.com/watch?v=fsi0aJ9yr2o); you'll be hooked by 1:28.
+
+That screencast is from 2012. In the meantime, Meteor has become a mature JavaScript-everywhere web
+development framework. Read more at [Why Meteor](http://www.meteorpedia.com/read/Why_Meteor).
+
+
+# Issues
+
+If you encounter an issue while using this package, please CC @dandv when you file it in this repo.
+
+
+# DONE
+
+* Automated and visual test for the fitRows layout
+
+
+# TODO
+
+* Add other tests; however, that is overkill, and the responsibiity of Isotope, not of the Meteor integration.
