### Tuwunel Configuration
###
### THIS FILE IS GENERATED. CHANGES/CONTRIBUTIONS IN THE REPO WILL BE
### OVERWRITTEN!
###
### You should rename this file before configuring your server. Changes to
### documentation and defaults can be contributed in source code at
### src/core/config/mod.rs. This file is generated when building.
###
### Any values pre-populated are the default values for said config option.
###
### At the minimum, you MUST edit all the config options to your environment
### that say "YOU NEED TO EDIT THIS".
###
### For more information, see:

# The server_name is the pretty name of this server. It is used as a
# suffix for user and room IDs/aliases.
#
# See the docs for reverse proxying and delegation:
# https://tuwunel.chat/deploying/generic.html#setting-up-the-reverse-proxy
#
# Also see the `[global.well_known]` config section at the very bottom.
#
# Examples of delegation:
# - https://matrix.org/.well-known/matrix/server
# - https://matrix.org/.well-known/matrix/client

# The default address (IPv4 or IPv6) tuwunel will listen on.

# "::1"]

#
# For reverse proxying, see:
# https://tuwunel.chat/deploying/generic.html#setting-up-the-reverse-proxy

# tuwunel cannot listen on both an IP address and a UNIX socket. If
# listening on a UNIX socket, you MUST remove/comment the `address` key.

# Remember to make sure that your reverse proxy has access to this socket
# file, either by adding your reverse proxy to the 'tuwunel' group or
