+        WELCOME TO TEAM 112'S CONSOLE BASED NOTES APP
+         
+        This application is a working console-based prototype for the
+        note taking application that the team will be delivering at the end of the term.
+        
+        With this simple app, users can:
+            1. Create Notes
+            2. Edit Notes
+            3. Delete Notes
+            
+         1. Create Notes
+            - To create notes, users must type "notes <filename>"
+            
+         2. Edit Notes
+            - To edit notes, users must type "notes <filename>"
+            - If the file doesn't exist, a new note will be created
+            
+         3. Delete Notes
+            - To delete a note, users must type "notes -d <filename>"
+            - If the user tries to delete a note that doesn't exist,
+              the app will display an error message
