 ## How to use
 
-You must have godot in your path
-
-First modify the *xmake.lua* to change the project name, and other configurations as needed.
-
-```lua
-
--- project name, this will be the output shared library name
-PROJECT_NAME = "gdexample"
-
--- project version
-VERSION = "0.0.1"
-
--- where is the godot project saved, default is "demo"
-GODOT_PROJECT_FOLDER = "demo"
-
--- where to save the export project, default is "publish"
-PUBLISH_FOLDER = "publish"
-
-```
-
-After change the configurations, you can run the following commands to build, run and export.
+You must have [godot](https://godotengine.org/) in your path
 
 ```sh
 
-# 1. gen gdextension file (only once)
-xmake gengdextension
+# 1. build the project
+xmake f -m debug && xmake
 
-# 2. build the project
-xmake
-
-# 3. open the editor at least once (works only in debug mode)
+# 2. open the editor at least once
 xmake run Editor

+# 6. generate a class that inherits from godot class, like Sprite2D
 # by default the generated files will save under "src" folder, you can change it by -d folder/under/src
 xmake ext-class -n MySprite2D -b Sprite2D -s myexample1 -d sample
 
-```
-
-For better support in vscode, you can use command "Xmake: UpdateIntellisense" to generate *compile_commands.json*, then update "compileCommands" field in *c_cpp_properties.json* to point to the file.

-NOTE: not tested on other platforms except windows and linux.
