+# RANDOM RECEIPT GENERATOR
+## Developer : Kenny Edelin
+
+### Main.java
+In this class, you will see my main method that allows my receipt to RUN.
+
+### Receipt.java
+In this class, you will see sections for User Inout, as well as Random Data generations. User Input, consist of my three question inquiring about Name, Budget and Vip code.
+
+### PriceGenerator.java
+In this class, you will see mostly random data generators. Generating item prices, as well as random discounts, mystery adjustments, tax rates and rounded totals.
+
+### CodeGenerator.java
+This class consist of if/else statements that build the receipt code. These if/else statements are based on the length of user input. There are also return statements to specify what my output should be.
+
+### ReceiptGenerator.java
+This class has all contents that the receipt includes, which in return calls for a lot of print statements. Also, I tried my best to separate each section on the receipt with hyphens.
+
+### CLOSING
+Thank you for using and analyzing my Random Receipt Generator with me!
