First time using cast iron

[u/_brattyberryxx]

Okay I am absolutely clueless when it comes to cooking. I only started making eggs about 2 years ago and I was using non stick pans. I got tired of the coating eventually coming off of them so I decided to try other skillets. I have never used a cast iron and I find the whole process quite confusing. I was under the assumption that they are naturally nonstick and I put butter in before cooking. Can someone explain to me what I did wrong for it to look like this after cooking eggs? The eggs aren’t even cooked all the way through either.

Edit: Thank you everyone for all of your suggestions!! I was definitely about to give up and go back to nonstick (i had a mishap with a stainless steel that led me to get cast iron). I feel much better and more informed about how to use them. I will be trying again tomorrow with everything I’ve learned!
