+OneRoll - High Performance Dice Expression Parser
+
+A dice expression parser implemented in Rust and bound to Python through PyO3.
+Supports complex dice expression parsing, various modifiers and mathematical operations.
+
+Main functions:
+- Basic Dice Rolling (XdY)
+- Mathematical operations (+, -, *, /, ^)
+- Modifiers support (!, kh, kl, dh, dl, r, ro)
+- Bracket support
+- Complete error handling
+
+Example of usage: 
+# Basic use 
+import oneroll 
+result = oneroll.roll("3d6 + 2") 
+print(result.total) # output total points 
+
+# Use the OneRoll class 
+roller = oneroll.OneRoll() 
+result = roller.roll("4d6kh3") 
+
+# Simple throw 
+total = oneroll.roll_simple(3, 6)
