Written by the members of the Mostly Harmless Alliance, the Hitchhiker's Code is a code of conduct for all members, detailing their rights, responsibilities, freedoms, and rules. This document is unique as it was compiled by various contributions from the MHA membership, not being written for them like a typical charter. This means the document truly belongs to the hitchhikers of the alliance. The Code was opened for contributions on February 22nd, 2008, and for the next few months, members of the alliance added their own segments to the treaty, which were composed together into the final document we have today.
