+            Dear reader.
+
+            This is a demo note. Also a short summary to help you get started in how to use create, edit
+            or delete note items.
+
+            1. Creating a note: Pretty easy actually. Just tap the button with the pen icon and type away.
+            To save your note, press back and exit the editing screen. And done! the note is saved :)
+
+            2. Editing a note: When you open a note, like this one, it is on reader mode, double tap on this text to enter editor mode, and make your changes.
+
+            3. Deleting a note: I think you know this one. Go back, swipe this note away, and its gone.
+
+            That's it! You're ready to go. Remember to give us feedback on the app and on changes you might wanna see in the future.
+            And don't forget to give us 5 stars ;)
+
+            ## TO COME ##
+            - Tasks : Like a todo list or whatever
+            - Voice recorder/ voice note : I'd like to integrate this nicely with text notes. Like taking text notes, record sound all in one note.
+            - Insights : See which apps you use the most, see which apps you haven't used in a long time,
+            probably to suggest clearing some, and some informative usage patterns, All while we're offline :)
+
+            Remember! All you need is less.

+            Thanks for the support
