Need help with front squats form

So after hearing some others on hear talk about the benefits of front squats, I tried them today for the first time just to mix in a different exercise. I’ve been doing back squats for some time, and while I wouldn’t say I’m strong in the back squat, I’ve made gains and feel like I can perform the exercise with good form. Today, I could not find a comfortable position to hold the bar in the front squat. Seemed like it was jamming into my clavicle and I ended up using more of my arms to support the bar. Very awkward. Any tips on what I can do to get more comfortable and improve my form? Where should the bar be resting? Thanks!
