The front page of your wiki is the first page that users see and acts as the table of contents for your site. Information on the front page should explain the purpose of your wiki, how you want users to participate and important pages that users can navigate to when getting started.
Now you change the name of your front page to more accurately reflect the purpose of your wiki.
To rename your page, choose edit and click ‘rename this page’.

I love aesthetic options like this. It’s not something you’d normally notice, but it does so much to make the wiki feel truly ‘yours’.
Thanks for this!
Since I started my wiki here I wondered why the frontpage was excluded from the renaming options. This is a small but nice QoL improvement.
Mine doesn’t give me this option ):
