Starting a Wildflower garden from dirt

Hi all! I’m really wanting to start a wildflower or a no cut garden this year. I have the place that I want to put it but the problem is the place I want to put it is literally just hard brown dirt that hasn’t been touched for years (except for when my dog digs in it, so it is diggable) there is no grass, no flowers, nothing. I’ve done some research but I can’t really find what I’m looking for I guess. What would be the process and steps to getting this dirt bed ready to be able to sow seeds?

Thank you!!!
