 - To ensure the tree displays correctly, use Cull Mode: Front for the tree trunk material.
 - To change the season, you can make one unique leaf material for all the trees and then change its color or texture to make them yellow.

 1. Place [godot-cpp](https://github.com/godotengine/godot-cpp) of the version you need in the godot-cpp folder
-2. Use the SCons command:
-```
-scons platform=windows target= ...

+```sh
+scons target=template_release platform=windows

 Or use [ready-made libraries](https://github.com/JekSun97/gdTree3D/releases)
 
-<img src="image/preview.png">
+## Using Docker to build this GDExtension

+For easier reproducibility, there is a Dockerfile provided for building binaries for Linux and Windows.
+
+```sh
+docker build -t tree3dbuilder:latest .
