You should mention that this is your alt account at https://community.fandom.com/wiki/User:EllieShay5 and vice versa or you could get blocked for sockpuppeting.
As for you question, you need to be an admin:
Go to the wiki's Main page
Click the triangle to the right of EDIT and select Edit mobile main page
Click the EDIT button under Wiki description
Change the text and click DONE at top right
Click PUBLISH at the top right
That should do it.
Thanks Fandyllic!
