The lack of "the" makes this read a bit weirdly:

>GitHub Package Registry allows you to develop your code and host your packages in one place. You can use packages from GitHub Package Registry as a dependency in your source code on GitHub.

"Package registry" is a fairly generic term, so to me it would be natural to refer to this product as "the Github package registry" (capitalized or not).

Is there a name for deliberately avoiding "the" in this way?
