 # Description
 
-Dynamic forecasting of PostgreSQL database performance. Problem. Solution. Why we built it.
+Hyperion: A PostgreSQL analytic tool to test and compare actual dynamic query runtimes with query runtimes calculated by PostgreSQL's EXPLAIN ANALYZE profiling tool. 
 
 # Features
 
-So many great features to come!
+> - Overview
+> - Databases 
+    >> - On the Database page, users can connect to their databases by either providing the database URI or manually providing connection details (host, port, database name, and user credentials)

+</center>
+
+> - Run Tests 
+    >> - On the Run Test page, users can select a database, and query. The run test function will then display the actual query runtime measured by the PostgreSQL server’s CPU clock time as well as query runtime provided via the explain analyze command and associated summary statistics (min, max, median, sd, q1,q3).
