+hapijs - sample app for benchmarking
+-----------------------------------
+
+## Setup
+
+run 
+```
+npm install 
+```
+
+and you're set!
+
+## Running
+
+```
+node index.js
+```
+
+## Note:
+update the postgres server uri in config/manifest.js
+
+## Known Issues
+If the postgres uri is not correct, the app will return 500 for any request.
+I'm unsure at this moment why the server doesn't report the error. Will look
+into it in the future.
