 The FreeBSD Project is run by around 500 committers , or developers who have commit access to the master source code repositories and can develop , debug or enhance any part of the system . Most of the developers are volunteers and few developers are paid by some companies . There are several kinds of committers , including source committers ( base operating system ) , doc committers ( documentation and web site authors ) and ports ( third party application porting and infrastructure ) . Every two years the FreeBSD committers select a 9 @-@ member FreeBSD Core Team who are responsible for overall project direction , setting and enforcing project rules and approving new <unk> , or the granting of <unk> commit access . A number of responsibilities are officially assigned to other development teams by the FreeBSD Core Team , for example , responsibility for managing the ports collection is delegated to the Ports Management Team .
