Hi, I am trying to upload the extension using the method here:

[https://www.slicer.org/wiki/Documentation/Nightly/Developers/Build\_ExtensionsIndex](https://www.slicer.org/wiki/Documentation/Nightly/Developers/Build_ExtensionsIndex)

But I don’t get a target for ExperimentalUpload. Is the documentation up to date? Below is what I got.

Thanks,  
Greg

Hi Greg,

Support for use of `ExperimentalUpload` has been removed when we simplified the extension build system.

The wiki page has been updated accordingly.

This works great now. Thanks!
