Website displays strangely and error when cloning

[JohannesKarge]

Hello,
this is my 3rd attempt of trying to build a website with GH and don't why why I am always running into problems even when following every step by step guide I could find.

1. I have forked/deployed and published my website here: johanneskarge.github.io. Can you explain why it doesnt display correctly?
2. Running: git clone git@github.com:USERNAME/username.git results in:
   Cloning into 'username'...
   git@github.com: Permission denied (publickey).
   fatal: Could not read from remote repository.
   Please make sure you have the correct access rights and the repository exists.
   Any guidance?
   I just want a simple website, in case you have an update to date guide on how to set this up I'd be glad!
   Many thanks, I am new to this! :)

Our install guide is already up-to-date. As for your questions:

1. We have an answer for that in our FAQ.
2. Just to be sure, you replaced the USERNAME part of the url with the correct link to your repository, right?
