-# SimpleDictionary
+# OpenDictionary
 This is an application for a simplistic on-the-go dictionary. 
 
-Purpose:
+**Purpose:**
 I made this application out of need because I needed something like this. To quickly add words and check them later without too much effort. Other applications have a cluttered interface where I have to bookmark words or star them in order to store them which is unnecessary. I have to read the meaning again for the next few days to remember it. So, instead of just looking at it once, I needed to store them locally.
 
-Functioning:
+**Functioning:**
 Just add the words you want to save in your own dictionary and view them later at any time you want.
 How to use instructions are given inside the application.

-Android Studio for development of application.<br>
-Volley API for making REST calls.<br>
-SQLite for creating Local Database.<br>
