+
+This project is used to compile a GDExtension (godot engine cpp extension), and try to use xmake to manage the project.
+
+Forked from [Github](https://github.com/chaosddp/gdextension-cpp-xmake-template)
+
+## Install xmake
+
+Install xmake from [here](https://xmake.io/#/guide/installation).
+
+## 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.
+
+```sh
+
+# 1. gen gdextension file (only once)
+xmake gengdextension
+
+# 2. build the project
+xmake
+
+# 3. open the editor at least once (works only in debug mode)
+xmake run Editor
+
+# 4. run the demo (works only in debug mode)
+xmake run
+
+# 5. export the project, the executable will be under "publish" folder by default
+xmake p
+
+# 6. clean the build and publish
+xmake clean
+
+# 7. 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.
