 There are two things distinguishing the presented model from the standard Public Good Game on 2D lattice.
 
-First, diversification of the interaction neighbourhoods leads to a decrease in the synergy factor required to achieve cooperation.
+First, diversification of the interaction neighbourhoods leads to a decrease of the synergy factor required to achieve cooperation. This can be observed by chooising *neighborhood-type* as "random von Neumann" or "random Moore".
 
-Second, by introducing a subpopulation of roaming agents, one can also decrease the synergy factor requited to achieve cooperation.
+Second, by introducing a subpopulation of roaming agents, one can also decrease the synergy factor requited to achieve cooperation. To observe this one needs to choose *neighborhood-type* as "random von Neumann", "random Moore", "K patches" or "random K patches. Netx, the participarion of the roaming agents can be controlled using *roaming-agents* slider.
