 [^socket]: Beszel only needs access to read container information. For [linuxserver/docker-socket-proxy](https://github.com/linuxserver/docker-socket-proxy) you would set `CONTAINERS=1`.
+[^memcalc]: The default value for used memory is based on gopsutil's [Used](https://pkg.go.dev/github.com/shirou/gopsutil/v4@v4.24.6/mem#VirtualMemoryStat) calculation, which should align fairly closely with `free`. Set `MEM_CALC` to `htop` to align with htop's calculation.
