+
+- Fix bug where attempting to send transactions with large number of EDUs can fail. ([\#5418](https://github.com/matrix-org/synapse/issues/5418))
+
+
+Improved Documentation
+----------------------
+
+- Expand the federation guide to include relevant content from the MSC1711 FAQ ([\#5419](https://github.com/matrix-org/synapse/issues/5419))
+
+
+Internal Changes
+----------------
+
+- Move password reset links to /_matrix/client/unstable namespace. ([\#5424](https://github.com/matrix-org/synapse/issues/5424))
+
+
+Synapse 1.0.0rc3 (2019-06-10)
+=============================
+
+Security: Fix authentication bug introduced in 1.0.0rc1. Please upgrade to rc3 immediately
+
+
+Synapse 1.0.0rc2 (2019-06-10)
+=============================
+
+Bugfixes
+--------
+
+- Remove redundant warning about key server response validation. ([\#5392](https://github.com/matrix-org/synapse/issues/5392))
+- Fix bug where old keys stored in the database with a null valid until timestamp caused all verification requests for that key to fail. ([\#5415](https://github.com/matrix-org/synapse/issues/5415))
+- Fix excessive memory using with default `federation_verify_certificates: true` configuration. ([\#5417](https://github.com/matrix-org/synapse/issues/5417))
+
+
+Synapse 1.0.0rc1 (2019-06-07)
+=============================
+
+Features
+--------
+
+- Synapse now more efficiently collates room statistics. ([\#4338](https://github.com/matrix-org/synapse/issues/4338), [\#5260](https://github.com/matrix-org/synapse/issues/5260), [\#5324](https://github.com/matrix-org/synapse/issues/5324))
+- Add experimental support for relations (aka reactions and edits). ([\#5220](https://github.com/matrix-org/synapse/issues/5220))
+- Ability to configure default room version. ([\#5223](https://github.com/matrix-org/synapse/issues/5223), [\#5249](https://github.com/matrix-org/synapse/issues/5249))
+- Allow configuring a range for the account validity startup job. ([\#5276](https://github.com/matrix-org/synapse/issues/5276))
+- CAS login will now hit the r0 API, not the deprecated v1 one. ([\#5286](https://github.com/matrix-org/synapse/issues/5286))
+- Validate federation server TLS certificates by default (implements [MSC1711](https://github.com/matrix-org/matrix-doc/blob/master/proposals/1711-x509-for-federation.md)). ([\#5359](https://github.com/matrix-org/synapse/issues/5359))
+- Update /_matrix/client/versions to reference support for r0.5.0. ([\#5360](https://github.com/matrix-org/synapse/issues/5360))
+- Add a script to generate new signing-key files. ([\#5361](https://github.com/matrix-org/synapse/issues/5361))
+- Update upgrade and installation guides ahead of 1.0. ([\#5371](https://github.com/matrix-org/synapse/issues/5371))

-Troubleshooting
-===============
-
-Running out of File Handles
----------------------------
-
-If synapse runs out of filehandles, it typically fails badly - live-locking
-at 100% CPU, and/or failing to accept new TCP connections (blocking the
-connecting client).  Matrix currently can legitimately use a lot of file handles,
-thanks to busy rooms like #matrix:matrix.org containing hundreds of participating
-servers.  The first time a server talks in a room it will try to connect
-simultaneously to all participating servers, which could exhaust the available
-file descriptors between DNS queries & HTTPS sockets, especially if DNS is slow
-to respond.  (We need to improve the routing algorithm used to be better than
-full mesh, but as of June 2017 this hasn't happened yet).
-
-If you hit this failure mode, we recommend increasing the maximum number of
-open file handles to be at least 4096 (assuming a default of 1024 or 256).
-This is typically done by editing ``/etc/security/limits.conf``
-
-Separately, Synapse may leak file handles if inbound HTTP requests get stuck
-during processing - e.g. blocked behind a lock or talking to a remote server etc.
-This is best diagnosed by matching up the 'Received request' and 'Processed request'
-log lines and looking for any 'Processed request' lines which take more than
-a few seconds to execute.  Please let us know at #synapse:matrix.org if
-you see this failure mode so we can help debug it, however.
-
-Help!! Synapse eats all my RAM!
--------------------------------
-
-Synapse's architecture is quite RAM hungry currently - we deliberately
-cache a lot of recent room data and metadata in RAM in order to speed up
-common requests.  We'll improve this in future, but for now the easiest
-way to either reduce the RAM usage (at the risk of slowing things down)
-is to set the almost-undocumented ``SYNAPSE_CACHE_FACTOR`` environment
-variable.  The default is 0.5, which can be decreased to reduce RAM usage
-in memory constrained enviroments, or increased if performance starts to
-degrade.
-
-Using `libjemalloc <http://jemalloc.net/>`_ can also yield a significant
-improvement in overall amount, and especially in terms of giving back RAM
-to the OS. To use it, the library must simply be put in the LD_PRELOAD
-environment variable when launching Synapse. On Debian, this can be done
-by installing the ``libjemalloc1`` package and adding this line to
-``/etc/default/matrix-synapse``::
-
-    LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libjemalloc.so.1
-
-This can make a significant difference on Python 2.7 - it's unclear how
-much of an improvement it provides on Python 3.x.

-Setting up Federation
-=====================
-
-Federation is the process by which users on different servers can participate
-in the same room. For this to work, those other servers must be able to contact
-yours to send messages.
-
-The ``server_name`` in your ``homeserver.yaml`` file determines the way that
-other servers will reach yours. By default, they will treat it as a hostname
-and try to connect to port 8448. This is easy to set up and will work with the
-default configuration, provided you set the ``server_name`` to match your
-machine's public DNS hostname, and give Synapse a TLS certificate which is
-valid for your ``server_name``.
-
-For a more flexible configuration, you can set up a DNS SRV record. This allows
-you to run your server on a machine that might not have the same name as your
-domain name. For example, you might want to run your server at
-``synapse.example.com``, but have your Matrix user-ids look like
-``@user:example.com``. (A SRV record also allows you to change the port from
-the default 8448).
-
-To use a SRV record, first create your SRV record and publish it in DNS. This
-should have the format ``_matrix._tcp.<yourdomain.com> <ttl> IN SRV 10 0 <port>
-<synapse.server.name>``. The DNS record should then look something like::
-
-    $ dig -t srv _matrix._tcp.example.com
-    _matrix._tcp.example.com. 3600    IN      SRV     10 0 8448 synapse.example.com.
-
-Note that the server hostname cannot be an alias (CNAME record): it has to point
-directly to the server hosting the synapse instance.
-
-You can then configure your homeserver to use ``<yourdomain.com>`` as the domain in

-        --config-path homeserver.yaml \
-        --generate-config
-    python -m synapse.app.homeserver --config-path homeserver.yaml
-
-If you've already generated the config file, you need to edit the ``server_name``
-in your ``homeserver.yaml`` file. If you've already started Synapse and a
-database has been created, you will have to recreate the database.
-
-If all goes well, you should be able to `connect to your server with a client`__,
-and then join a room via federation. (Try ``#matrix-dev:matrix.org`` as a first
-step. "Matrix HQ"'s sheer size and activity level tends to make even the
-largest boxes pause for thought.)
-
-.. __: `Connecting to Synapse from a client`_
-
-Troubleshooting
----------------
-
-You can use the `federation tester <https://matrix.org/federationtester>`_ to
-check if your homeserver is all set.
-
-The typical failure mode with federation is that when you try to join a room,
-it is rejected with "401: Unauthorized". Generally this means that other
-servers in the room couldn't access yours. (Joining a room over federation is a
-complicated dance which requires connections in both directions).
-
-So, things to check are:
-
-* If you are not using a SRV record, check that your ``server_name`` (the part
-  of your user-id after the ``:``) matches your hostname, and that port 8448 on
-  that hostname is reachable from outside your network.
-* If you *are* using a SRV record, check that it matches your ``server_name``
-  (it should be ``_matrix._tcp.<server_name>``), and that the port and hostname
-  it specifies are reachable from outside your network.
-
-Another common problem is that people on other servers can't join rooms that
-you invite them to. This can be caused by an incorrectly-configured reverse
-proxy: see `<docs/reverse_proxy.rst>`_ for instructions on how to correctly
-configure a reverse proxy.
-
-Running a Demo Federation of Synapses
--------------------------------------
-
-If you want to get up and running quickly with a trio of homeservers in a
-private federation, there is a script in the ``demo`` directory. This is mainly
-useful just for development purposes. See `<demo/README>`_.
-
 
 Using PostgreSQL
 ================
 
-As of Synapse 0.9, `PostgreSQL <https://www.postgresql.org>`_ is supported as an
-alternative to the `SQLite <https://sqlite.org/>`_ database that Synapse has
-traditionally used for convenience and simplicity.
+Synapse offers two database engines:
+ * `SQLite <https://sqlite.org/>`_
+ * `PostgreSQL <https://www.postgresql.org>`_
 
-The advantages of Postgres include:
+By default Synapse uses SQLite in and doing so trades performance for convenience.
+SQLite is only recommended in Synapse for testing purposes or for servers with
+light workloads.
+
+Almost all installations should opt to use PostreSQL. Advantages include:
 
 * significant performance improvements due to the superior threading and
   caching model, smarter query optimiser

+Troubleshooting
+===============
+
+Running out of File Handles
+---------------------------
+
+If synapse runs out of file handles, it typically fails badly - live-locking
+at 100% CPU, and/or failing to accept new TCP connections (blocking the
+connecting client).  Matrix currently can legitimately use a lot of file handles,
+thanks to busy rooms like #matrix:matrix.org containing hundreds of participating
+servers.  The first time a server talks in a room it will try to connect
+simultaneously to all participating servers, which could exhaust the available
+file descriptors between DNS queries & HTTPS sockets, especially if DNS is slow
+to respond. (We need to improve the routing algorithm used to be better than
+full mesh, but as of March 2019 this hasn't happened yet).
+
+If you hit this failure mode, we recommend increasing the maximum number of
+open file handles to be at least 4096 (assuming a default of 1024 or 256).
+This is typically done by editing ``/etc/security/limits.conf``
+
+Separately, Synapse may leak file handles if inbound HTTP requests get stuck
+during processing - e.g. blocked behind a lock or talking to a remote server etc.
+This is best diagnosed by matching up the 'Received request' and 'Processed request'
+log lines and looking for any 'Processed request' lines which take more than
+a few seconds to execute. Please let us know at #synapse:matrix.org if
+you see this failure mode so we can help debug it, however.
+
+Help!! Synapse eats all my RAM!
+-------------------------------
+
+Synapse's architecture is quite RAM hungry currently - we deliberately
+cache a lot of recent room data and metadata in RAM in order to speed up
+common requests. We'll improve this in the future, but for now the easiest
+way to either reduce the RAM usage (at the risk of slowing things down)
+is to set the almost-undocumented ``SYNAPSE_CACHE_FACTOR`` environment
+variable. The default is 0.5, which can be decreased to reduce RAM usage
+in memory constrained enviroments, or increased if performance starts to
+degrade.
+
+Using `libjemalloc <http://jemalloc.net/>`_ can also yield a significant
+improvement in overall amount, and especially in terms of giving back RAM
+to the OS. To use it, the library must simply be put in the LD_PRELOAD
+environment variable when launching Synapse. On Debian, this can be done
+by installing the ``libjemalloc1`` package and adding this line to
+``/etc/default/matrix-synapse``::
+
+    LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libjemalloc.so.1
+
+This can make a significant difference on Python 2.7 - it's unclear how
+much of an improvement it provides on Python 3.x.

+Upgrading to v1.0
+=================
+
+Validation of TLS certificates
+------------------------------
+
+Synapse v1.0 is the first release to enforce
+validation of TLS certificates for the federation API. It is therefore
+essential that your certificates are correctly configured. See the `FAQ
+<docs/MSC1711_certificates_FAQ.md>`_ for more information.
+
+Note, v1.0 installations will also no longer be able to federate with servers
+that have not correctly configured their certificates.
+
+In rare cases, it may be desirable to disable certificate checking: for
+example, it might be essential to be able to federate with a given legacy
+server in a closed federation. This can be done in one of two ways:-
+
+* Configure the global switch ``federation_verify_certificates`` to ``false``.
+* Configure a whitelist of server domains to trust via ``federation_certificate_verification_whitelist``.
+
+See the `sample configuration file <docs/sample_config.yaml>`_
+for more details on these settings. 
+
+Email
+-----
+When a user requests a password reset, Synapse will send an email to the 
+user to confirm the request.
+
+Previous versions of Synapse delegated the job of sending this email to an
+identity server. If the identity server was somehow malicious or became
+compromised, it would be theoretically possible to hijack an account through
+this means.
+
+Therefore, by default, Synapse v1.0 will send the confirmation email itself. If
+Synapse is not configured with an SMTP server, password reset via email will be
+disabled.
+
+To configure an SMTP server for Synapse, modify the configuration section
+headed ``email``, and be sure to have at least the ``smtp_host``, ``smtp_port``
+and ``notif_from`` fields filled out. You may also need to set ``smtp_user``,
+``smtp_pass``, and ``require_transport_security``.
+
+If you are absolutely certain that you wish to continue using an identity
+server for password resets, set ``trust_identity_server_for_password_resets`` to ``true``.
+
+See the `sample configuration file <docs/sample_config.yaml>`_
+for more details on these settings.

+# Setup Synapse with Workers and Systemd
+
+This is a setup for managing synapse with systemd including support for
+managing workers. It provides a `matrix-synapse`, as well as a
+`matrix-synapse-worker@` service for any workers you require. Additionally to
+group the required services it sets up a `matrix.target`. You can use this to
+automatically start any bot- or bridge-services. More on this in
+[Bots and Bridges](#bots-and-bridges).
+
+See the folder [system](system) for any service and target files.
+
+The folder [workers](workers) contains an example configuration for the
+`federation_reader` worker. Pay special attention to the name of the
+configuration file. In order to work with the `matrix-synapse-worker@.service`
+service, it needs to have the exact same name as the worker app.
+
+This setup expects neither the homeserver nor any workers to fork. Forking is
+handled by systemd.
+
+## Setup
+
+1. Adjust your matrix configs. Make sure that the worker config files have the
+exact same name as the worker app. Compare `matrix-synapse-worker@.service` for
+why. You can find an example worker config in the [workers](workers) folder. See
+below for relevant settings in the `homeserver.yaml`.
+2. Copy the `*.service` and `*.target` files in [system](system) to
+`/etc/systemd/system`.
+3. `systemctl enable matrix-synapse.service` this adds the homeserver
+app to the `matrix.target`
+4. *Optional.* `systemctl enable
+matrix-synapse-worker@federation_reader.service` this adds the federation_reader
+app to the `matrix-synapse.service`
+5. *Optional.* Repeat step 4 for any additional workers you require.
+6. *Optional.* Add any bots or bridges by enabling them.
+7. Start all matrix related services via `systemctl start matrix.target`
+8. *Optional.* Enable autostart of all matrix related services on system boot
+via `systemctl enable matrix.target`
+
+## Usage
+
+After you have setup you can use the following commands to manage your synapse
+installation:
+
+```
+# Start matrix-synapse, all workers and any enabled bots or bridges.
+systemctl start matrix.target
+
+# Restart matrix-synapse and all workers (not necessarily restarting bots
+# or bridges, see "Bots and Bridges")
+systemctl restart matrix-synapse.service
+
+# Stop matrix-synapse and all workers (not necessarily restarting bots
+# or bridges, see "Bots and Bridges")
+systemctl stop matrix-synapse.service
+
+# Restart a specific worker (i. e. federation_reader), the homeserver is
+# unaffected by this.
+systemctl restart matrix-synapse-worker@federation_reader.service
+
+# Add a new worker (assuming all configs are setup already)
+systemctl enable matrix-synapse-worker@federation_writer.service
+systemctl restart matrix-synapse.service
+```
+
+## The Configs
+
+Make sure the `worker_app` is set in the `homeserver.yaml` and it does not fork.
+
+```
+worker_app: synapse.app.homeserver 
+daemonize: false
+```
+
+None of the workers should fork, as forking is handled by systemd. Hence make
+sure this is present in all worker config files.
+
+```
+worker_daemonize: false
+```
+
+The config files of all workers are expected to be located in
+`/etc/matrix-synapse/workers`. If you want to use a different location you have
+to edit the provided `*.service` files accordingly.  
+
+## Bots and Bridges
+
+Most bots and bridges do not care if the homeserver goes down or is restarted.
+Depending on the implementation this may crash them though. So look up the docs
+or ask the community of the specific bridge or bot you want to run to make sure
+you choose the correct setup.
+
+Whichever configuration you choose, after the setup the following will enable
+automatically starting (and potentially restarting) your bot/bridge with the
+`matrix.target`.
+
+```
+systemctl enable <yourBotOrBridgeName>.service
+```
+
+**Note** that from an inactive synapse the bots/bridges will only be started with
+synapse if you start the `matrix.target`, not if you start the
+`matrix-synapse.service`. This is on purpose. Think of `matrix-synapse.service`
+as *just* synapse, but `matrix.target` being anything matrix related, including
+synapse and any and all enabled bots and bridges.
+
+### Start with synapse but ignore synapse going down
+
+If the bridge can handle shutdowns of the homeserver you'll want to install the
+service in the `matrix.target` and optionally add a
+`After=matrix-synapse.service` dependency to have the bot/bridge start after
+synapse on starting everything.
+
+In this case the service file should look like this.
+
+```
+[Unit]
+# ...
+# Optional, this will only ensure that if you start everything, synapse will
+# be started before the bot/bridge will be started.
+After=matrix-synapse.service
+
+[Service]
+# ...
+
+[Install]
+WantedBy=matrix.target
+```
+
+### Stop/restart when synapse stops/restarts
+
+If the bridge can't handle shutdowns of the homeserver you'll still want to
+install the service in the `matrix.target` but also have to specify the
+`After=matrix-synapse.service` *and* `BindsTo=matrix-synapse.service`
+dependencies to have the bot/bridge stop/restart with synapse.
+
+In this case the service file should look like this.
+
+```
+[Unit]
+# ...
+# Mandatory
+After=matrix-synapse.service
+BindsTo=matrix-synapse.service
+
+[Service]
+# ...
+
+[Install]

+required that all servers present valid TLS certificates on their federation

+Setting up Federation
+=====================
+
+Federation is the process by which users on different servers can participate
+in the same room. For this to work, those other servers must be able to contact
+yours to send messages.
+
+The ``server_name`` configured in the Synapse configuration file (often
+``homeserver.yaml``) defines how resources (users, rooms, etc.) will be
+identified (eg: ``@user:example.com``, ``#room:example.com``). By
+default, it is also the domain that other servers will use to
+try to reach your server (via port 8448). This is easy to set
+up and will work provided you set the ``server_name`` to match your
+machine's public DNS hostname, and provide Synapse with a TLS certificate
+which is valid for your ``server_name``.
+
+Once federation has been configured, you should be able to join a room over
+federation. A good place to start is ``#synapse:matrix.org`` - a room for
+Synapse admins.
+
+
+## Delegation
+
+For a more flexible configuration, you can have ``server_name``
+resources (eg: ``@user:example.com``) served by a different host and
+port (eg: ``synapse.example.com:443``). There are two ways to do this:
+
+- adding a ``/.well-known/matrix/server`` URL served on ``https://example.com``.
+- adding a DNS ``SRV`` record in the DNS zone of domain
+  ``example.com``.
+
+Without configuring delegation, the matrix federation will
+expect to find your server via ``example.com:8448``. The following methods
+allow you retain a `server_name` of `example.com` so that your user IDs, room
+aliases, etc continue to look like `*:example.com`, whilst having your
+federation traffic routed to a different server.
+
+### .well-known delegation
+
+To use this method, you need to be able to alter the
+``server_name`` 's https server to serve the ``/.well-known/matrix/server``
+URL. Having an active server (with a valid TLS certificate) serving your
+``server_name`` domain is out of the scope of this documentation.
+
+The URL ``https://<server_name>/.well-known/matrix/server`` should
+return a JSON structure containing the key ``m.server`` like so:
+
+    {
+	    "m.server": "<synapse.server.name>[:<yourport>]"
+    }
+
+In our example, this would mean that URL ``https://example.com/.well-known/matrix/server``
+should return:
+
+    {
+	    "m.server": "synapse.example.com:443"
+    }
+
+Note, specifying a port is optional. If a port is not specified an SRV lookup
+is performed, as described below. If the target of the
+delegation does not have an SRV record, then the port defaults to 8448.
+
+Most installations will not need to configure .well-known. However, it can be
+useful in cases where the admin is hosting on behalf of someone else and
+therefore cannot gain access to the necessary certificate. With .well-known,
+federation servers will check for a valid TLS certificate for the delegated
+hostname (in our example: ``synapse.example.com``).
+
+.well-known support first appeared in Synapse v0.99.0. To federate with older
+servers you may need to additionally configure SRV delegation. Alternatively,
+encourage the server admin in question to upgrade :).
+
+### DNS SRV delegation
+
+To use this delegation method, you need to have write access to your
+``server_name`` 's domain zone DNS records (in our example it would be
+``example.com`` DNS zone).
+
+This method requires the target server to provide a
+valid TLS certificate for the original ``server_name``.
+
+You need to add a SRV record in your ``server_name`` 's DNS zone with
+this format:
+
+     _matrix._tcp.<yourdomain.com> <ttl> IN SRV <priority> <weight> <port> <synapse.server.name>
+
+In our example, we would need to add this SRV record in the
+``example.com`` DNS zone:
+
+     _matrix._tcp.example.com. 3600 IN SRV 10 5 443 synapse.example.com.
+
+Once done and set up, you can check the DNS record with ``dig -t srv
+_matrix._tcp.<server_name>``. In our example, we would expect this:
+
+    $ dig -t srv _matrix._tcp.example.com
+    _matrix._tcp.example.com. 3600    IN      SRV     10 0 443 synapse.example.com.
+
+Note that the target of a SRV record cannot be an alias (CNAME record): it has to point
+directly to the server hosting the synapse instance.
+
+### Delegation FAQ
+#### When do I need a SRV record or .well-known URI?
+
+If your homeserver listens on the default federation port (8448), and your
+`server_name` points to the host that your homeserver runs on, you do not need an SRV
+record or `.well-known/matrix/server` URI.
+
+For instance, if you registered `example.com` and pointed its DNS A record at a
+fresh server, you could install Synapse on that host,
+giving it a `server_name` of `example.com`, and once [ACME](acme.md) support is enabled,
+it would automatically generate a valid TLS certificate for you via Let's Encrypt
+and no SRV record or .well-known URI would be needed.
+
+This is the common case, although you can add an SRV record or
+`.well-known/matrix/server` URI for completeness if you wish.
+
+**However**, if your server does not listen on port 8448, or if your `server_name`
+does not point to the host that your homeserver runs on, you will need to let
+other servers know how to find it. The way to do this is via .well-known or an
+SRV record.
+
+#### I have created a .well-known URI. Do I still need an SRV record?
+
+As of Synapse 0.99, Synapse will first check for the existence of a .well-known
+URI and follow any delegation it suggests. It will only then check for the
+existence of an SRV record.
+
+That means that the SRV record will often be redundant. However, you should
+remember that there may still be older versions of Synapse in the federation
+which do not understand .well-known URIs, so if you removed your SRV record
+you would no longer be able to federate with them.
+
+It is therefore best to leave the SRV record in place for now. Synapse 0.34 and
+earlier will follow the SRV record (and not care about the invalid
+certificate). Synapse 0.99 and later will follow the .well-known URI, with the
+correct certificate chain.
+
+#### Can I manage my own certificates rather than having Synapse renew certificates itself?
+
+Yes, you are welcome to manage your certificates yourself. Synapse will only
+attempt to obtain certificates from Let's Encrypt if you configure it to do
+so.The only requirement is that there is a valid TLS cert present for
+federation end points.
+
+#### Do you still recommend against using a reverse proxy on the federation port?
+
+We no longer actively recommend against using a reverse proxy. Many admins will
+find it easier to direct federation traffic to a reverse proxy and manage their
+own TLS certificates, and this is a supported configuration.
+
+See [reverse_proxy.rst](reverse_proxy.rst) for information on setting up a
+reverse proxy.
+
+#### Do I still need to give my TLS certificates to Synapse if I am using a reverse proxy?
+
+Practically speaking, this is no longer necessary.
+
+If you are using a reverse proxy for all of your TLS traffic, then you can set
+`no_tls: True` in the Synapse config. In that case, the only reason Synapse
+needs the certificate is to populate a legacy `tls_fingerprints` field in the
+federation API. This is ignored by Synapse 0.99.0 and later, and the only time
+pre-0.99 Synapses will check it is when attempting to fetch the server keys -
+and generally this is delegated via `matrix.org`, which will be running a modern
+version of Synapse.
+
+#### Do I need the same certificate for the client and federation port?
+
+No. There is nothing stopping you from using different certificates,
+particularly if you are using a reverse proxy. However, Synapse will use the
+same certificate on any ports where TLS is configured.
+
+## Troubleshooting
+
+You can use the [federation tester](
+<https://matrix.org/federationtester>) to check if your homeserver is
+configured correctly. Alternatively try the [JSON API used by the federation tester](https://matrix.org/federationtester/api/report?server_name=DOMAIN).
+Note that you'll have to modify this URL to replace ``DOMAIN`` with your
+``server_name``. Hitting the API directly provides extra detail.
+
+The typical failure mode for federation is that when the server tries to join
+a room, it is rejected with "401: Unauthorized". Generally this means that other
+servers in the room could not access yours. (Joining a room over federation is
+a complicated dance which requires connections in both directions).
+
+Another common problem is that people on other servers can't join rooms that
+you invite them to. This can be caused by an incorrectly-configured reverse
+proxy: see [reverse_proxy.rst](<reverse_proxy.rst>) for instructions on how to correctly
+configure a reverse proxy.

+## Running a Demo Federation of Synapses

+If you want to get up and running quickly with a trio of homeservers in a
+private federation, there is a script in the ``demo`` directory. This is mainly
+useful just for development purposes. See [demo/README](<../demo/README>).
