Needing advice aboy baby led weaning

Hi, I noticed on a post the other day a lot of mamas suggested baby led weaning. I have a few questions regarding this. At what age did you start your LO? What foods did you start with? Did you not worry about your LO choking? I make all my own baby food for my 6 month old but I am very curious about this way of feeding my little one especially after doing a bit of research.
