No problem, ref added.

If you're using Visual Editor, on the top of the edit area, right below the buttons for bold & italics, there's an "Insert ▾" button. Clicking on it gives a dropdown menu which includes "Reference". Click on it and paste the url (website link) into the pop-up window. Click "Insert" and the ref is added to the article. Make sure to save your edit before leaving & you're done.

If you're using source editor, see Help:Cite.
