 # System Roles
 
-There are several roles which are required to properly operate the QKM system. While it is possible to have an individual perform multiple roles, typically they should only perform one role at a time. It is also recommended to have at least 2 individuals, or ideally the full quorum be used to make decisions pertaining to QKM.
+There are several roles which are required to properly operate the QKM system. While it is possible to have an individual perform multiple roles, typically they should only perform one role at a time. It is also recommended to have at least 2 individuals, or ideally the full quorum be used to make decisions pertaining to QKM. At least 2 individuals are required for [level 2](threat-model.md#adversary-1).
 
 To better understand why the different roles are required, refer to the [selecting a quorum](selecting-quorum.md) and [threat model](threat-model.md) sections which enumerate a number of assumptions around pertinent threats to the system as well as the use of a quorum.
