Help! I'm buying a GF sourdough starter from Azure.

My husband is a Celiac and I've decided to completely cut it from our home for good. I've always been interested in Sourdough but never tried it, even a glutenous one. I'm buying a starter from someone who got it from Azure Standard. I plan on feeding it King Auther gluten free flour as I have a Costco membership and can get a 5lb bag for $8.

Does anyone have any good tried and true recipes for GF sourdough? Sandwich loaves but also things like muffins and cookies. I've looked over Google and they're all few and far between from what I've seen. We aren't vegan or dairy free so I'm not worried about that. I've seen sourdough discard crackers, does anyone have a GF version?

Also, since this is my first sourdough starter could someone walk me through the process of it? I have the basic idea but tips are always nice.

If there are any other things you guys can think of please let me know. Really looking forward to this experience, I'm just hoping I don't kill my starter too many times lol.
