-A web app to store hierarchial data
+
+So, you know all that client information you need to keep track of, like passwords and servers? Or how about all those serial keys for the software you have? meta is a webapp to organize these kinds of data for easier reference.
+
+##Organizing Data
+
+Meta has a four-level hierarchy 
+
+1. Genre
+	* The broadest category. An example could be titled 'Client Data'
+2. Category
+	* A general item in the genre. For example, an individual client.
+3. Section
+	* A grouping of label-data pairs. Something like 'CMS Access'
+4. Data
+	* Pairs of labels and values. 
+		
+		Eg. Username : admin
+		
+		
+This basic hierarchy enables keeping track of simple data in a neat fashion.
