-- 打包BlenderPlugins目录为zip文件。
-- 下载并安装Blender3.6 LTS版本。
-- 在 首选项=>插件 中安装打包的.zip文件
-- 打开DBMT面板，选择DBMT-GUI.exe所在路径完成插件初始化。
+# Installation Steps
+- Pack the BlenderPlugins directory into a zip file.
+- Download and install Blender version 4.2 LTS.
+- In Preferences => Add-ons, install the packed .zip file.
+- Open the DBMT panel, select the path where DBMT-GUI.exe is located to complete the plugin initialization.

+# Development Environment
 - Visual Studio Code
-- Python 3.9
-- Blender 3.6 LTS
-- pip install fake-bpy-module-3.6
-- pip install numpy
+- Python 3.12.7 or higher
+- Blender 4.2 LTS
+- `pip install fake-bpy-module-4.2`
+- `pip install numpy`
 
+# Notice
+- fake-bpy-module-4.2 need at least Python 3.12 to work.
+- VSCode is the best practice IDE in blender plugin development.
+- Ctrl + Shift + P to start debug Blender.
