 ## Overview
 
-This project implements a Red-Black Tree based key-value store (`RedBlockTreeKV`) that stores complex value structures efficiently. The implementation is particularly beneficial for use cases involving frequent insertions and deletions, as it reuses storage slots and minimizes gas consumption.
+This project implements a Red-Black Tree based key-value store (`RedBlackTreeKV`) that stores complex value structures efficiently. The implementation is particularly beneficial for use cases involving frequent insertions and deletions, as it reuses storage slots and minimizes gas consumption.
 
 The Red-Black Tree implementation is based on [Solady's RedBlackTreeLib](https://github.com/vectorized/solady/blob/main/src/utils/RedBlackTreeLib.sol). In this example, we modified the `remove` function to prevent deleting storage when removing nodes, enabling storage slot reuse for subsequent insertions.
