 ### Bootstrap process
 
 The bootstrap process is responsible for keeping the routing table filled and
-healthy throughout time. It runs once on startup, then periodically with a
-configurable frequency (default: 5 minutes).

-On every run, we generate a random peer ID and we look it up via the process

+Implementations may diverge from this base algorithm as long as they adhere to
