If you read the announcement there are some basic details for it, but in essence it will be controlled using smart contracts, code itself, rather than just by the team. The core team will have a 1/3 vote, 1/3 will be those that mine or buy it, and 1/3 will be a board of advisors nominated by both the team and the community at large. (some flow charts and such are on the way explaining this in more detail)
