How to edit attribute information

I need help figuring out how to do this, I dont know how to word it, and I cant find help anywhere.
Okay, so I have this Structure Attribute called "AppName"
"AppName" Has multiple lines of text being displayed on one of my pages. How do I edit the text being displayed, or how do I make a new one to override this attribute? I cant find where to write the text they need. please help, thank you

Hello Isaac,

I strongly recommend you to complete the Online Training for beginners, as this topic is covered there.

To edit text data you need a text input. Usually in a form. But without knowing from where comes the data and for where it must be saved, its impossible to help you.

Please, complete the online training
