it was basically:

1. adding a string to the config
2. restarting the node
3. entering two commands (now that i think about it, maybe the first command wouldn't be necessary if my node would be "older"/ better connected)

so easy - everyone can do it? probably not, but the experience was pleasant. now comes the harder part on my end. i want to understand what i did there. i did it this time without understand because we wanted to use the nearly empty mempool to save some precious sats
