Coaches Competitive Coaching at 15

[Gymnastics15]

Hi, I am a gymnast who had to take about a 6-month break from gymnastics due to mental health issues. I recently met back with my head coach/ gym owner to talk about coming back to gymnastics and catching up. He suggested I start coaching pre-team/ bronze to get myself back into the gym and after my shift having time to myself to work on rebuilding my skills. I am 15 years old, and I'd say I have a decent amount of knowledge when it comes to gymnastics and coaching. As this has been something, I've always wanted to coach for as long as I can remember. My question is, how do I go about this? Anything I should know before as I think about taking on this role?
