 If you place a file in the same path as your talk, with the same name as your
 talk, and only replace the ``.md`` suffix by ``.css``. Then the rendering engine
 will use this file:
-https://github.com/bast/cicero/blob/master/cicero/templates/render.html#L11-L13
+https://github.com/bast/cicero/blob/main/cicero/templates/render.html#L11-L13
 
 In other words, if your talk is called ``mytalk.md`` and you want to customize CSS,
 place a file called ``mytalk.css`` in the same place as your ``mytalk.md``.
 
 With this you can even override CSS directives and style your slides to your
 heart's content.
