 ## Summary
 
 The idea is that we want something we can use to plot GPS coordinates on a map and filter data based on our needs.
-For now it should: assign different colors to each cluster/class, and filter points based on a given time range.

 For Test data you'll be given a CSV file; which will be a subset of data we have in our database. 
 It'll be 2 - 4 weeks worth.

 You're task is to get the data, and be able to read/parse it. I recommend using [Papa Parser](http://papaparse.com/) to

+
+This is a big step. This is where most of the Javascript programming will happen. 
+If I had to break this down into 2 steps I would say:
+
+#### 1: Just put points on the Map
+
+Just plot the points onto the map.
+
+#### 2: Assign Colors to Clusters
+
+Assign points colors according to their cluster/class.
+
+### 5: Add Time Range Filter Control
+
+I would imagine implementing this with a slider or two text fields that take a **begin time**, and an **end time**.
+The idea is to just plot points that are within the two time ranges (inclusively) (i.e. 1/3/2015 - 1/5/2015 should include all points within those tow days and everytnig in between).

+### More?
+
+If you manage to get this far, we have other features that would be cool additions.

+### Help?
+
+You can contact us, and ask questions on Github Issues; which you can populate yourself, and I'll add stuff too.
