## It's recommended to also set 'ROCKET_CLI_COLORS=off'
# LOG_FILE=/path/to/log
## Disable icon downloading
## Set to true to disable icon downloading, this would still serve icons from $ICON_CACHE_FOLDER,
## but it won't produce any external network request. Needs to set $ICON_CACHE_TTL to 0,
## otherwise it will delete them and they won't be downloaded again.
# DISABLE_ICON_DOWNLOAD=false
