Not sure what you're asking, but git/other commands are giving you lots of feedback on what's wrong about the things you're typing.
For example, you added an url as a remote named origin, when trying to push to it it said that doesn't seem to be a git repository - if you type that url into a browser, you'll get a 404 not found - so no, that isn't a git repository
Also, you created a new repository in a new location and added whatever files happened to be there, so I wouldn't expect that to be a valid website. The idea was to use jekyll to generate a website, create a repository in that location, commit it, push it. You probably still have that website directory in your file system, so the next thing to do would be to navigate there and make sure there's a commit and that the right remote is added, then push
