Understanding insurance

Hey all, so, I'm only a M1 but mad people in my life come up to me with questions about insurance, different plans, HMOs, etc, etc. acting like I should know all of this (and honestly I probably should though), I've been on Medicaid most of my adult life so my knowledge doesn't extend much beyond what I've personally dealt with. What is a decent, succinct, resource I could go through to have the knowledgebase to answer the ins and outs of insurance-based questions? Thanks!
