         HOW TO USE HAPPY CODING
    =================================

    STEP 1: GET STARTED
    - Start with creating a username - this will allow you to save your progress.
    - The details of creating a username are in Step 2.
    - Next, select a programming language you would like to learn.
    - Then, select the level of difficulty you would like to begin with, and start coding!

    STEP 2: CREATE A USERNAME
    - Create a username - you may use a combination of letters, numbers and special symbols.
    - Note: You may get an error if the username already exists, in that case you must try a different one.
    - Once your username is created, you can log in using the 'Enter Your Username' option.
