Honestly, the confusion makes total sense; GitHub does a great job of hiding this stuff. Here's what's going on: those markdown files only exist right now as a proposed change sitting on a branch. That's the whole reason you can only get to them through the pull link, and nowhere else. They become a real, permanent part of the repo the moment you merge them in. And since it's your repo, that merge is yours to do, no special GitHub-fu required. Open the PR page (https://github.com/tobiaskreidl/Citrix-Tobias-Kreidl-Collection/pull/1), scroll down a bit, and click the green Merge pull request button. That's the "commit" step you were asking about.
There's one wrinkle worth knowing about, and it's the real reason none of this shows up on your main repo page. Your repository has a couple of branches. Your existing PDFs and the Word doc live on a branch called XenServer-Articles, so I pointed my PR at that same branch to drop the markdown right next to them. But the page GitHub shows when someone visits your repo is a different branch called main, which at the moment only holds a README. So even after you merge, the articles will sit on XenServer-Articles, not on that front page. That's actually been true of your PDFs all along; it's nothing my PR changed.
If you'd like the articles to show up on the landing page too, there are two easy ways, and I'm happy to do either one for you. We can change the repo's default branch to XenServer-Articles in Settings > Branches, so that one becomes the front page. Or I open a second small PR copying everything over to main. Just tell me which you'd rather have.
So the short version: merge the PR to make the markdown real, then we can decide whether you also want the front page pointing at the articles. No rush at all on that second part.
