Ask HN: Startup company formation contract

We are about to move from the "hobby" stage of our startup to a full fledged company. I am looking for a contract template which we can use to define company ownership, share details etc. I remember seeing somebody posted a link on HN to a great one a few days ago but I can't seem to find it!

Sorry to post this on HN, but I would really like to find it again! (if I remember correctly the site it was on was relatively new and the contracts were provided free of charge)
