The High Lords of Terra declare one of the 26 foundings and inform the AdMech that uses one of the tithes of Gene-seed that all Chapters send back, so the AdMech can check for corruption etc. The Founding Chapter from which the gene-seed is derived, then sends a cadre of elite Space Marines that train the new neophytes the ways of the parent chapter, the elite Marines are then incorporated into the new Chapter to become its Chapter Master and high ranking Marines. The AdMech also supplies the new Chapter with new gear, ships, tanks, armour, weapons etc. Then they go off and find a nice planet to settle down on, or not, depending.
