How to start meditating?

I’ve never been consistent with meditation and find it hard to make time..like when I should do it etc but if I do it just for 5 minutes a day to start outside, what do I do? Just focus on my breathing? I’m trying to learn to change my life, which comes with changing a mindset that’s been conditioned to feel validation from the approval of others, and people pleasing. I want to learn to turn inward, which I have an ADHD brain that constantly has noise of some sort, never quiet in my head even when it is quiet.

Any advice would be appreciated, thank you
