22+**A note on memory**: By default, the Urbit runtime needs 2GB of free memory,
23+and will fail to boot without it. Urbit usually only uses a portion of this, so
24+it's possible to use a swap file to makeup for a shortfall without degrading
25+performance. For instructions on how to configure a swap file on Linux, see
26+[this linuxize.com guide](https://linuxize.com/post/create-a-linux-swap-file/).
28+**A note on storage**: Urbit saves every event it processes to its [Event
29+Log](https://developers.urbit.org/reference/glossary/eventlog). This means its
30+disk usage slowly grows over time. Until event log truncation is implemented,
31+it's advisable to have 40 or 50GB of disk space available, so you don't have to
32+worry about running out for a long time. If you don't have that much, your ship
33+will still run fine, but you may run out of space some months down the line.
