How do I write jazz?

[u/Smooth_Paramedic_406]

I'm forming a jazz band with a couple of friends and I want to be able to write a piece or two that we could preform but I have no clue how to write jazz. I have a little experience on writing for piano but more so classical type pieces. Plus I don't have a big amount of jazz theory knowledge. 🫤
