 # React Tic-Tac-Toe
 
+## Please Read First!
+
+The digital campus' version of Tic-Tac-Toe differs from the original in the following ways:
+- We will *not* be using `main` branch. Follow step 6 in the **One-Time Project Setup** to change branches.
+- Wave 1 has been completed for you; however, it would help you understand the flow of data by reviewing the code written for Wave 1.
+- Wave 3's `checkForWinner` function has been created for you; however, read through Wave 3 instructions to figure out how and where to use it.
