Question How to do simple leg inverse kinematics?

Hello, I'm looking to add simple inverse kinematic legs to my player character, but I'm really not even sure where to start. I've found plenty of tutorials and plenty of (even free) assets available, but still struggling to understand how I should go about it in regards to the player model I have (which is fairly simple, though I made it so I can also add whatever else I might need in blender). Can anyone point me towards any good tutorials or resources that are a little more comprehensive and break it down a bit more step by step, basically for dummies? Thanks

 

Anyone? Sadly I'm an idiot so I struggle with this stuff more than most people probably do, I can't make heads or tails of any of these tutorials or assets and need something that'll explain it to me like I'm 5. Any help is appreciated, thanks
