 * If you are going to use the machine, make sure no one else is using it.
 * No formal booking system, just ask in discord.
 * When you are done with it, leave it as clean as possible: no stale images running, try to organize folders, etc.

+## Running simulations
+
+We have a simple tool [nwaku-simulator](https://github.com/alrevuelta/nwaku-simulator/) that allows running some simple simulations with up to 100/200 nwaku nodes, configured with discv5 and using a bootstrap node to connect to each other. This tool also scraps metrics and exposes them in a grafana dashboard. It can be run with just two commands with a configurable amount of nodes and a given release version. See instructions in repo.
