New, need guidance on form

Hi guys. I am new to running. I've been strength, and pilates training for years and ready for a new workout. I am starting to run and loving it. Started about a week ago. I've been running every day a few miles each day. Today I ran 4 and I am so proud of myself. now i am very slow, maybe a speed 6 on a treadmill, and find myself getting in my head about my form even though I don't know what I am supposed to look like. I hear "run with your hips" but likeeee what does that even mean.

My question is, it seems like I have the stamina for it going at a slow and steady pace, but I am wondering: what's the best form? Im really trying not to Injure myself.

( right now, I stretch and do a little walk before I run, and then stretch after my run as well) I am a 6 foot female if that matters. Thank you
