+# AOI (Area of Interest) Library
 
-#### 目前实现：
-- 九宫格
-- 四叉树
+This library provides implementations of Area of Interest algorithms for spatial partitioning. Currently, it includes implementations for the following algorithms:
+
+1. **九宫格 (Grid Manager)**
+   - A simple grid-based AOI algorithm dividing the area into a grid of cells and associating entities with the corresponding grid cells.
+
+2. **四叉树 (Quadtree)**
+   - A hierarchical spatial partitioning algorithm dividing the area into four quadrants recursively, optimizing the search for entities within a specified range.
+
+## Usage:
+
+### 九宫格 (Grid Manager)
+
+```go
+// Example Usage:
+aoiManager := NewGridManager(startX, startY, areaWidth, gridCount)
+aoiManager.Add(x, y, "Entity1")
+aoiManager.Delete(x, y, "Entity1")
+result := aoiManager.Search(x, y)
+
+// Example Usage:
+quadTree := NewQuadTree(startX, startY, areaWidth)
+quadTree.Add(x, y, "Entity1")
+quadTree.Delete(x, y, "Entity1")
+result := quadTree.Search(x, y)
+```
+
+## Features:
+- Both implementations support adding, deleting, and searching for entities within a specified area of interest.
+- The Grid Manager uses a simple grid-based approach, while the Quadtree provides a hierarchical and optimized solution for larger and dynamic environments.
+
+## TODO:
+Implement additional commonly used AOI algorithms:
+- R-树 (R-tree)
+- 六边形网格 (Hexagonal Grid)
+- 基于事件的算法 (Event-driven Approaches)
