 # Containers-Stack
-A dead stupid stack implementation, but one fully working with super cool coverage:)

-## Example
-
-``` 
-| aStack |
- aStack := CTStack new.
- aStack push: 'a'.
- aStack size >>> 1.
- aStack push: 'b'.
- aStack size >>> 2.
- aStack top >>> 'b'.
- aStack size >>> 2.
- aStack pop  >>> 'b'.
- aStack size >>> 1.
- aStack pop >>> 'a'.
- aStack size >>> 0. 
- ```
+A High-performance, Array based Stack implementation providing efficient LIFO (Last In, First Out) operations with fixed capacity and proper bounds checking.

+## What is a Stack?
+
+A Stack is a linear data structure that follows the LIFO (Last In, First Out) principle. Elements are added and removed from the same end, called the "top" of the stack. Think of it like a stack of plates - you can only add or remove plates from the top.
+
+### Key Benefits
+- **O(1) Performance**: Constant time push, pop, and top operations
+- **Fixed Memory Usage**: Array-based implementation with bounded capacity
+- **Memory Safe**: Automatic cleanup prevents memory leaks
+- **Simple API**: Clean, intuitive interface following standard conventions
+- **Robust Error Handling**: Proper stack overflow and underflow protection
