+Configuration file format
+-------------------------
- An effort should be made to keep the individual imports in alphabetical
- order.
+The `sample configuration file <./sample_config.yaml>`_ acts as a reference to
+Synapse's configuration options for server administrators. Remember that many
+readers will be unfamiliar with YAML and server administration in general, so
+that it is important that the file be as easy to understand as possible, which
+includes following a consistent format.
- If the list becomes long, wrap it with parentheses and split it over
- multiple lines.
+Some guidelines follow:
- - As per `PEP-8 <https://www.python.org/dev/peps/pep-0008/#imports>`_,
- imports should be grouped in the following order, with a blank line between
- each group:
+* Sections should be separated with a heading consisting of a single line
+ prefixed and suffixed with ``##``. There should be **two** blank lines
+ before the section header, and **one** after.
- 1. standard library imports
- 2. related third party imports
- 3. local application/library specific imports
+* Each option should be listed in the file with the following format:
- - Imports within each group should be sorted alphabetically by module name.
+ * A comment describing the setting. Each line of this comment should be
+ prefixed with a hash (``#``) and a space.
- - Avoid wildcard imports (``from synapse.types import *``) and relative
- imports (``from .types import UserID``).
+ The comment should describe the default behaviour (ie, what happens if
+ the setting is omitted), as well as what the effect will be if the
+ setting is changed.
+
+ Often, the comment end with something like "uncomment the
+ following to \<do action>".
+
+ * A line consisting of only ``#``.
+
+ * A commented-out example setting, prefixed with only ``#``.
+
+ For boolean (on/off) options, convention is that this example should be
+ the *opposite* to the default (so the comment will end with "Uncomment
+ the following to enable [or disable] \<feature\>." For other options,
+ the example should give some non-default value which is likely to be
+ useful to the reader.
+
+* There should be a blank line between each option.
+
+* Where several settings are grouped into a single dict, *avoid* the
+ convention where the whole block is commented out, resulting in comment
+ lines starting ``# #``, as this is hard to read and confusing to
+ edit. Instead, leave the top-level config option uncommented, and follow
+ the conventions above for sub-options. Ensure that your code correctly
+ handles the top-level option being set to ``None`` (as it will be if no
+ sub-options are enabled).
+
+* Lines should be wrapped at 80 characters.
+
+Example::
+
+ ## Frobnication ##
+
+ # The frobnicator will ensure that all requests are fully frobnicated.
+ # To enable it, uncomment the following.
+ #
+ #frobnicator_enabled: true
+
+ # By default, the frobnicator will frobnicate with the default frobber.
+ # The following will make it use an alternative frobber.
+ #
+ #frobincator_frobber: special_frobber
+
+ # Settings for the frobber
+ #
+ frobber:
+ # frobbing speed. Defaults to 1.
+ #
+ #speed: 10
+
+ # frobbing distance. Defaults to 1000.
+ #
+ #distance: 100
+
+Note that the sample configuration is generated from the synapse code and is
+maintained by a script, ``scripts-dev/generate_sample_config``. Making sure
+that the output from this script matches the desired format is left as an
+exercise for the reader!

+ # If no configuration is provided, a single job will be set up to delete expired
+ # events in every room daily.
+ #
+ # Each job's configuration defines which range of message lifetimes the job
+ # takes care of. For example, if 'shortest_max_lifetime' is '2d' and
+ # 'longest_max_lifetime' is '3d', the job will handle purging expired events in
+ # rooms whose state defines a 'max_lifetime' that's both higher than 2 days, and

+ # 'longest_max_lifetime' of '3d' will handle every room with a retention policy
+ # which 'max_lifetime' is lower than or equal to three days.
+ #
+ # The rationale for this per-job configuration is that some rooms might have a
+ # retention policy with a low 'max_lifetime', where history needs to be purged
+ # of outdated messages on a very frequent basis (e.g. every 5min), but not want
