Wiki often contains important set-up instructions, reporting instructions, etc (an example where wiki instructions are really important). People mostly arrive through the wiki page, so it's not a problem. But sometimes, people might arrive directly through https://testdays.fedoraproject.org homepage (getting a link from https://fedoraproject.org/wiki/QA/Test_Days or elsewhere), and in that case, it's not very obvious that they should read the wiki first, before starting working on the test cases.

Let's make the link to the wiki more obvious, and clarify that people should read it first, before they start testing. This should be just a slight tweak to the existing UI, nothing fancy.
