Good for you. Finding a beginners meeting is a great way to start. I attend a beginners meeting on Friday nights. It is a very nice mix of people with long term sobriety and newcomers. Formats differ but at the meeting I attend people go around the table and introduce themselves. A general question "is this anyone's first AA meeting in life?" is asked. Newcomers are welcomed to the group and with most meetings an introductory packet is handed around and members of the same sex as the newcomer write their name and phone number on the packet which is provided to the newcomer. The phone numbers are those of people who you can call if you are struggling and need someone to talk to.
A topic is discussed relating to the program. Sometimes it is how to cope with urges. Or what if you are angry. Or the first three steps. Someone, usually the chairperson, gives a lead and then it is open to discussion. You don't have to talk. You can sit and listen if that is what you prefer.
It is welcoming. Good job on two days.
