looking for tutorial/example for adding unlimited txt string fields in addon options

[Tati Booyakah]

Hello...
I am designing a addon and I was wondering if someone could point me in the direction for a tutorial/example.
What I am looking for is to create a txt sting field that keeps adding another field every time I need to add a sting.
Basically unlimited txt string fields.

I hope this makes sense
Thank You!
