+ # CALCULATOR DEMO PROJECT
+
+ * This is a simple calculator that performs simple arithmetic operations for:
+    *  Addition(+)
+    * Subtraction (-)
+    * Multiplication(*)
+    * Division(/)
+ * The Calculator is built in C programming language.
+
+ ### How to Use the Calculator:
+
+ 1. Compile the Calculator.c file using:
+ ```
+ gcc -Wall -pedantic -Werror -Wextra -std=gnu89 Calculator.c -o Calculator
+ ```
+To run the executable file generated:
+
+```
+./Calculator
+```
+- The Calculator will prompt the user to enter the first number
+- Next prompt will be for the second number
+
+- Finally, it'll prompt the user to enter the allowed arithmetic operator
+
+## ENJOY THE USE
