+### (1) Installation
+
+1. Open the Package Manager from `Window` -> `Package Manager`.
+2. Find and click the + button in the upper lefthand corner of the window. Select `Add package from git URL`.
+3. Enter the following URL:
+```
+https://github.com/SarahWeiii/CoACD.git?path=/Packages/info.flandre.coacd#unity
+```
+4. Click `Add`.
+
+### (2) Usage
+
+1. Add a `CoACD` component to your object. You can tweak the parameters in the editor.
+2. Right click the component header lane. Then select `Generate Collision Meshes` or
+ `Generate Collision Meshes for Hierarchy` to generate collision for the current object or
+ all children of the current object that contains a `MeshFilter`, respectively.

+
+3. Unity mesh colliders will be created in the scene under `Collision` as a child of each object.

+
+4. Alternatively, you can call the runtime API as a method of the `CoACD` component:
+
+```csharp
+public List<Mesh> RunACD(Mesh mesh);
+```
