Dear developers，  
I want to upload the extension created by myself, [ExtensionsIndex/.github/PULL\_REQUEST\_TEMPLATE.md at main · Slicer/ExtensionsIndex · GitHub](https://github.com/Slicer/ExtensionsIndex/blob/main/.github/PULL_REQUEST_TEMPLATE.md#todo-list-for-submitting-a-new-extension)  
Is this the tutorial about how to making it?  
Best wishes,  
Joshua

Yes that checklist is helpful; there is also this description of the release process: [Extensions — 3D Slicer documentation](https://slicer.readthedocs.io/en/latest/developer_guide/extensions.html#distribute-an-extension)

Thanks, I also wonder how to do it offline to just test the extension on my own computer, is there any tutorial?
