+# Sticky Notes
+
+A gui based notes keeping app that is designed to be handy, fast and efficient for small notes that you take throughout the day. It uses python's in-built gui library tkinter.
+
+## Usage
+
+- Copy the contents of the folder into your desired location
+- Run the command `pip install -r requirements.txt`
+- Execute the script `python sticky_notes.py`
+
+   ### Getting started
+   This application is intuitive and easy to use. The layout consists of a list view and 4 buttons :-
+   - Add a note - Adds the content of the text box as a new note
+   - Delete a note - Deletes the highlighted note
+   - Check item - Checks the selected item, i.e., marks it as done
+   - Uncheck item - Unchecks the selected item.
+
