 When duniter-ts starts up, the WS2P module accesses the peer cards stored in duniter-ts's database following synchronization.
 
-## Priority of WS2P connections
+## Priority of WS2P outcoming connections

+The WS2P module attempts to establish outcoming connections at the kick-start of the node and then every 10 minutes.  
+At each attempt, all known endpoints are contacted until the outcoming quota is reached.
