How to implement a gallery is unclear

Your instructions in the FAQs about how to upload images says to see the gallery settings. But I don’t see any. I wish the instructions were more step-step. You should tell people to 1. make a page, 2. Click on Add Media, 3. Create Gallery, 4. Look in right sidebar of gallery creation page to find configurations. With the lack of understanding, I wasted time to figure all of this out only to find no configuration options in the gallery settings. Any idea as to why there are no settings?
