If you want to publish plugins of your own, you can use the following command:

```powershell
# install xrfeitoria first
cd xrfeitoria
pip install .

# build plugins for UE 5.1, UE 5.2, and UE 5.3 on Windows
python -m xrfeitoria.utils.publish_plugins build-unreal `
    -u "C:/Program Files/Epic Games/UE_5.1/Engine/Binaries/Win64/UnrealEditor-Cmd.exe" `
    -u "C:/Program Files/Epic Games/UE_5.2/Engine/Binaries/Win64/UnrealEditor-Cmd.exe" `
    -u "C:/Program Files/Epic Games/UE_5.3/Engine/Binaries/Win64/UnrealEditor-Cmd.exe"

# build plugins for Blender
python -m xrfeitoria.utils.publish_plugins build-blender
```
