How do I change the default "Home About Author Collection Portal"

on the top left when you’re given a website basically id like to remove “collection, author, portal and about”

also on the bottom left where it shows “contact contribute” I would like to change contribute to About but going into the ghost dashboard and pages it doesn’t work when I try changing the name

If you want to change the top navigation then update it from Settings > Navigation > Primary Navigation

You see secondary Navigation too there under primary navigation. Just change the link and label from there.
