+# Tools
+
+The developer need to know the loaded data whether is correct when testing LibCmo.
+So we create this folder and you can use Unvirt and the tools located in this folder to test the correction of loaded data.
+
+Unvirt can show the data of each CKObject, such as Texture, Mesh and etc. 
+For example, Unvirt can provide vertex's position, normal, UV, even the face's indices data for CKMesh. 
+You can use tools to broswer memory to get them, but you couldn't evaluate them how they shape a mesh. 
+This is the reason why this folder existed and in this README I will tell you how to debug the loaded data.
+
+## Memory Inspector
+
+I suggest you to use HxD to broswer memory, but if you have other softwares which you have been familiar with, use it freely.
+
+## CKTexture Debugging
+
+* Install [PixelViewer](https://github.com/carina-studio/PixelViewer) first.
+* Change profile to `BGRA_8888` (actually is little-endian RGBA8888, but I think the developer of PixelViewer get confused).
+* The image resolution can be gotten from Uvirt. Set it in PixelViewer.
+* The image address also can be gotten from Unvirt. Save the image data from memory to local file and open it by PixelViewer.
+
+## CKMesh Debugging
+
+See [MeshConv README](./MeshConv/README.md)
