Co-Dependents Anonymous (CoDA) is a set of informal self-help groups made up of men and women with a common interest in working through the problems that co-dependency has caused in their lives. CoDA is based on AA (Alcoholics Anonymous) and uses an adapted version of their 12 Steps and Traditions as a central part of its suggested programme of recovery. 

All meetings begin with an introduction which usually includes the 12 Steps and Traditions, a welcome to newcomers, and an explanation of the format the meeting will take. There may be a speaker, or a reading of a Step or a topic. The meeting is then open for people to share their experiences, feelings and recovery with the group. There is no obligation to share if you do not wish to, whether you are a newcomer or a long-established member. Each meeting usually incorporates a collection to cover the expenses of the group (eg hire of the meeting room) but CoDA is non-profit making. The meeting will end with a special prayer, called the Serenity Prayer. After the meeting, newcomers who would like more information can use this time to have their questions answered by more established members.
