    ## Server ##
    
    # The domain name of the server, with optional explicit port.
    # This is used by remote servers to connect to this server,
    # e.g. matrix.org, localhost:8080, etc.
    # This is also the last part of your UserID.

    # CPU affinity mask. Setting this restricts the CPUs on which the
    # process will be scheduled. It is represented as a bitmask, with the
    # lowest order bit corresponding to the first logical CPU and the
    # highest order bit corresponding to the last logical CPU. Not all CPUs
    # may exist on a given system but a mask may specify more CPUs than are
    # present.
    #
    # For example:
    #    0x00000001  is processor #0,
    #    0x00000003  is processors #0 and #1,
    #    0xFFFFFFFF  is all processors (#0 through #31).
    #
    # Pinning a Python process to a single CPU is desirable, because Python
    # is inherently single-threaded due to the GIL, and can suffer a
    # 30-40% slowdown due to cache blow-out and thread context switching
    # if the scheduler happens to schedule the underlying threads across
    # different cores. See
    # https://www.mirantis.com/blog/improve-performance-python-programs-restricting-single-cpu/.

    # List of ports that Synapse should listen on, their purpose and their
    # configuration.
    #
    # Options for each listener include:
    #
    #   port: the TCP port to bind to
    #
    #   bind_addresses: a list of local addresses to listen on. The default is
    #       'all local interfaces'.
    #
    #   type: the type of listener. Normally 'http', but other valid options are:
    #       'manhole' (see docs/manhole.md),
    #       'metrics' (see docs/metrics-howto.rst),
    #       'replication' (see docs/workers.rst).
    #
    #   tls: set to true to enable TLS for this listener. Will use the TLS
    #       key/cert specified in tls_private_key_path / tls_certificate_path.
    #
    #   x_forwarded: Only valid for an 'http' listener. Set to true to use the
    #       X-Forwarded-For header as the client IP. Useful when Synapse is
    #       behind a reverse-proxy.
    #
    #   resources: Only valid for an 'http' listener. A list of resources to host
    #       on this port. Options for each resource are:
    #
    #       names: a list of names of HTTP resources. See below for a list of
    #           valid resource names.
    #
    #       compress: set to true to enable HTTP comression for this resource.
    #
    #   additional_resources: Only valid for an 'http' listener. A map of
    #        additional endpoints which should be loaded via dynamic modules.
    #
    # Valid resource names are:
    #
    #   client: the client-server API (/_matrix/client). Also implies 'media' and

    #   keys: the key discovery API (/_matrix/keys).
    #
    #   media: the media API (/_matrix/media).
    #
    #   metrics: the metrics interface. See docs/metrics-howto.rst.
    #
    #   openid: OpenID authentication.
    #
    #   replication: the HTTP replication API (/_synapse/replication). See
    #       docs/workers.rst.
    #
    #   static: static resources under synapse/static (/_matrix/static). (Mostly
    #       useful for 'fallback authentication'.)
    #
    #   webclient: A web client. Requires web_client_location to be set.

    ## TLS ##
    
    # PEM-encoded X509 certificate for TLS.
    # This certificate, as of Synapse 1.0, will need to be a valid and verifiable
    # certificate, signed by a recognised Certificate Authority.
    #
    # See 'ACME support' below to enable auto-provisioning this certificate via
    # Let's Encrypt.
    #
    #tls_certificate_path: "CONFDIR/SERVERNAME.tls.crt"
    
    # PEM-encoded private key for TLS
    #
    #tls_private_key_path: "CONFDIR/SERVERNAME.tls.key"
    
    # ACME support: This will configure Synapse to request a valid TLS certificate
    # for your configured `server_name` via Let's Encrypt.
    #
    # Note that provisioning a certificate in this way requires port 80 to be
    # routed to Synapse so that it can complete the http-01 ACME challenge.
    # By default, if you enable ACME support, Synapse will attempt to listen on
    # port 80 for incoming http-01 challenges - however, this will likely fail
    # with 'Permission denied' or a similar error.
    #
    # 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.
    #
    acme:
        # ACME support is disabled by default. Uncomment the following line
        # (and tls_certificate_path and tls_private_key_path above) to enable it.
        #
        #enabled: true
    
        # Endpoint to use to request certificates. If you only want to test,
        # use Let's Encrypt's staging url:
        #     https://acme-staging.api.letsencrypt.org/directory
        #
        #url: https://acme-v01.api.letsencrypt.org/directory
    
        # Port number to listen on for the HTTP-01 challenge. Change this if
        # you are forwarding connections through Apache/Nginx/etc.
        #
        #port: 80
    
        # Local addresses to listen on for incoming connections.
        # Again, you may want to change this if you are forwarding connections

    # If synapse is run behind a load balancer that handles the TLS then it
    # will be necessary to add the fingerprints of the certificates used by
    # the loadbalancers to this list if they are different to the one
    # synapse is using.

    # Homeservers are permitted to cache the list of TLS fingerprints
    # returned in the key responses up to the "valid_until_ts" returned in

    # responses have passed before deploying it.

    #
    # Parts of this section are required if enabling the 'consent' resource under
    # 'listeners', in particular 'template_dir' and 'version'.
    #
    # '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
    # guest users unless 'send_server_notice_to_guests' is set to true.
    #
    # 'block_events_error', if set, will block any attempts to send events
    # until the user consents to the privacy policy. The value of the setting is
    # used as the text of the error.
    #
    # 'require_at_registration', if enabled, will add a step to the registration
    # process, similar to how captcha works. Users will be required to accept the
    # policy before their account is created.
    #
    # 'policy_name' is the display name of the policy users will see when registering
    # for an account. Has no effect unless `require_at_registration` is enabled.
    # Defaults to "Privacy Policy".

    # Server Notices room configuration
    #
    # Uncomment this section to enable a room which can be used to send notices
    # from the server to users. It is a special room which cannot be left; notices
    # come from a special "notices" user id.
    #
    # 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
    # notices.
    #
    # It's also possible to override the room name, the display name of the
    # "notices" user, and the avatar for the user.
    #
    #server_notices:
    #  system_mxid_localpart: notices
    #  system_mxid_display_name: "Server Notices"
    #  system_mxid_avatar_url: "mxc://server.com/oumMVlgDnLYFaPVkExemNVVZ"

    # 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:
