+# Countroll - Description
+
+Countroll is designed to make using counting bots a bit more interesting. It turns integers into complex, unreadable 
+mathematical expressions, perfect for showing off your mathematical knowledge to you friends!
+Countroll uses the following operators to make your integer as complex as possible
+
+- Addition | +
+- Subtraction | +
+- Multiplication | *
+- Division | /
+- Square Root | sqrt()
+- Exponentiation | ^
+
+## Compatibility

+Countroll is currently only compatible with [Numselli's counting bot](https://counting.numselli.xyz/), although I hope to be able to support more counting bots soon!
