+have installed customised templates, or leave it unset to use the default
+templates.

 Windows Install
 ---------------
-Synapse can be installed on Cygwin. It requires the following Cygwin packages:
-
-- gcc
-- git
-- libffi-devel
-- openssl (and openssl-devel, python-openssl)
-- python
-- python-setuptools
-
-The content repository requires additional packages and will be unable to process
-uploads without them:
-
-- libjpeg8
-- libjpeg8-devel
-- zlib
-
-If you choose to install Synapse without these packages, you will need to reinstall
-``pillow`` for changes to be applied, e.g. ``pip uninstall pillow`` ``pip install
-pillow --user``
-
-Troubleshooting:
-
-- You may need to upgrade ``setuptools`` to get this to work correctly:
-  ``pip install setuptools --upgrade``.
-- You may encounter errors indicating that ``ffi.h`` is missing, even with
-  ``libffi-devel`` installed. If you do, copy the ``.h`` files:
-  ``cp /usr/lib/libffi-3.0.13/include/*.h /usr/include``
-- You may need to install libsodium from source in order to install PyNacl. If
-  you do, you may need to create a symlink to ``libsodium.a`` so ``ld`` can find
-  it: ``ln -s /usr/local/lib/libsodium.a /usr/lib/libsodium.a``

+        # - it plays badly with the server-side rate-limiter, which starts tarpitting you

+        #   working through the backlog of your requests, which you have already timed
+        #   out.
+        #
+        # - for this request in particular, we now (as of
+        #   https://github.com/matrix-org/synapse/pull/3456) reject any PDUs where the
+        #   server can't produce a plausible-looking set of prev_events - so we becone
+        #   much more likely to reject the event.
+        #
+        # - contrary to what it says above, we do *not* fall back to fetching fresh state
+        #   for the room if get_missing_events times out. Rather, we give up processing
+        #   the PDU whose prevs we are missing, which then makes it much more likely that

+        #   requests taking 8 hours to process. It's not entirely clear why that was going
