+#
+# There are a couple of potential solutions to this:
+#
+#  * If you already have an Apache, Nginx, or similar listening on port 80,
+#    you can configure Synapse to use an alternate port, and have your web
+#    server forward the requests. For example, assuming you set 'port: 8009'
+#    below, on Apache, you would write:
+#
+#    ProxyPass /.well-known/acme-challenge http://localhost:8009/.well-known/acme-challenge
+#
+#  * Alternatively, you can use something like \`authbind\` to give Synapse
+#    permission to listen on port 80.

+
+## Ratelimiting ##
+
+# Ratelimiting settings for client actions (registration, login, messaging).
+#
+# Each ratelimiting configuration is made of two parameters:
+#   - per_second: number of requests a client can send per second.
+#   - burst_count: number of requests a client can send before being throttled.
+#
+# Synapse currently uses the following configurations:
+#   - one for messages that ratelimits sending based on the account the client
+#     is using
+#   - one for registration that ratelimits registration requests based on the
+#     client's IP address.
+#   - one for login that ratelimits login requests based on the client's IP
+#     address.
+#   - one for login that ratelimits login requests based on the account the
+#     client is attempting to log into.
+#   - one for login that ratelimits login requests based on the account the
+#     client is attempting to log into, based on the amount of failed login
+#     attempts for this account.
+#   - one for ratelimiting redactions by room admins. If this is not explicitly
+#     set then it uses the same ratelimiting as per rc_message. This is useful
+#     to allow room admins to deal with abuse quickly.
+#
+# The defaults are as shown below.
+#
+#rc_message:
+#  per_second: 0.2
+#  burst_count: 10
+#

+#     a window before the server will delay processing the request.
+#   - sleep_delay: duration in milliseconds to delay processing events
+#     from remote servers by if they go over the sleep limit.
+#   - reject_limit: maximum number of concurrent federation requests
+#     allowed from a single server
+#   - concurrent: number of federation requests to concurrently process
+#     from a single server
+#
+# The defaults are as shown below.

+#
+# Parts of this section are required if enabling the 'consent' resource under

+#
+# 'template_dir' gives the location of the templates for the HTML forms.
+# This directory should contain one subdirectory per language (eg, 'en', 'fr'),
+# and each language directory should contain the policy document (named as
+# '<version>.html') and a success page (success.html).
+#
+# 'version' specifies the 'current' version of the policy document. It defines
+# the version to be served by the consent resource if there is no 'v'
+# parameter.
+#
+# 'server_notice_content', if enabled, will send a user a "Server Notice"
+# asking them to consent to the privacy policy. The 'server_notices' section
+# must also be configured for this to work. Notices will *not* be sent to

+#
+# If you uncomment this section, you *must* define the system_mxid_localpart
+# setting, which defines the id of the user which will be used to send the

+#
+#enable_room_list_search: false
+
+# The \`alias_creation\` option controls who's allowed to create aliases
+# on this server.
+#
+# The format of this option is a list of rules that contain globs that
+# match against user_id, room_id and the new alias (fully qualified with
+# server name). The action in the first rule that matches is taken,
+# which can currently either be "allow" or "deny".
+#
+# Missing user_id/room_id/alias fields default to "*".
+#
+# If no rules match the request is denied. An empty list means no one
+# can create aliases.
+#
+# Options for the rules include:
+#
+#   user_id: Matches against the creator of the alias
+#   alias: Matches against the alias being created
+#   room_id: Matches against the room ID the alias is being pointed at
+#   action: Whether to "allow" or "deny" the request if the rule matches

+# which rooms can be published in the public room list.
+#
+# The format of this option is the same as that for
+# \`alias_creation_rules\`.
+#
+# If the room has one or more aliases associated with it, only one of
+# the aliases needs to match the alias rule. If there are no aliases
+# then only rules with \`alias: *\` match.
+#
+# If no rules match the request is denied. An empty list means no one
+# can publish rooms.
+#
+# Options for the rules include:
+#
+#   user_id: Matches agaisnt the creator of the alias
+#   room_id: Matches against the room ID being published
+#   alias: Matches against any current local or canonical aliases
+#            associated with the room
+#   action: Whether to "allow" or "deny" the request if the rule matches

+# The default is:
+#
+#room_list_publication_rules:
+#  - user_id: "*"
+#    alias: "*"
+#    room_id: "*"
+#    action: allow
+
+
+# Server admins can define a Python module that implements extra rules for
+# allowing or denying incoming events. In order to work, this module needs to
+# override the methods defined in synapse/events/third_party_rules.py.
+#
+# This feature is designed to be used in closed federations only, where each
+# participating server enforces the same rules.

+
+## Opentracing ##
+
+# These settings enable opentracing, which implements distributed tracing.
+# This allows you to observe the causal chains of events across servers
+# including requests, key lookups etc., across any server running
+# synapse or any other other services which supports opentracing
+# (specifically those implemented with Jaeger).
