Hey @theMomax !
First of all thank you for your work! I've been waiting for that feature 
Unfortunately, I am encountering an error when calling generate-documentation to generate a documentation:
swift package \
--allow-writing-to-directory "./docs" \
generate-documentation \
--disable-indexing \
--hosting-base-path "MyPackage" \
--included-extended-types \
--output-path "./docs" \
--target "MyPackage" \
--transform-for-static-hosting
Output:
Building for debugging...
Build complete! (0.17s)
Generating documentation for 'MyPackage'...
Building for debugging...
Build complete! (0.14s)
Converting documentation...
Error: Unknown option '--included-extended-types'
Usage: docc convert [<options>] <source-bundle-path>
See 'docc convert --help' for more information.
error: 'docc convert' invocation failed with a nonzero exit code: '64'
However, the call below works fine and I can see Extended Modules section:
swift package --disable-sandbox preview-documentation --target "MyPackage" --include-extended-types
Could you point me where I did a mistake or it is a bug?
The option is --include-extended-types, not --included-extended-types - looks like a tiny hard-to-spot typo.

@ethankusters would be worth to tweak the release notes with --include-extended-types in description to prevent potential situations like I had
