+
+# Configuring Synapse
+
+This is intended as a guide to the Synapse configuration. The behavior of a Synapse instance can be modified
+through the many configuration settings documented here — each config option is explained,
+including what the default is, how to change the default and what sort of behaviour the setting governs.
+Also included is an example configuration for each setting. If you don't want to spend a lot of time
+thinking about options, the config as generated sets sensible defaults for all values. Do note however that the
+database defaults to SQLite, which is not recommended for production usage. You can read more on this subject
+[here](../../setup/installation.md#using-postgresql).
+
+## Config Conventions
+
+Configuration options that take a time period can be set using a number
+followed by a letter. Letters have the following meanings:
+
+* `s` = second
+* `m` = minute
+* `h` = hour
+* `d` = day
+* `w` = week
+* `y` = year
+
+For example, setting `redaction_retention_period: 5m` would remove redacted
+messages from the database after 5 minutes, rather than 5 months.
+
+In addition, configuration options referring to size use the following suffixes:
+
+* `K` = KiB, or 1024 bytes
+* `M` = MiB, or 1,048,576 bytes
+* `G` = GiB, or 1,073,741,824 bytes
+* `T` = TiB, or 1,099,511,627,776 bytes
+
+For example, setting `max_avatar_size: 10M` means that Synapse will not accept files larger than 10,485,760 bytes
+for a user avatar.
+
+## Config Validation
+
+The configuration file can be validated with the following command:
+```bash
+python -m synapse.config read <config key to print> -c <path to config>
+```
+
+To validate the entire file, omit `read <config key to print>`:
+```bash
+python -m synapse.config -c <path to config>
+```
+
+To see how to set other options, check the help reference:
+```bash
+python -m synapse.config --help
+```
+
+### YAML
+The configuration file is a [YAML](https://yaml.org/) file, which means that certain syntax rules
+apply if you want your config file to be read properly. A few helpful things to know:
+* `#` before any option in the config will comment out that setting and either a default (if available) will
+   be applied or Synapse will ignore the setting. Thus, in example #1 below, the setting will be read and
+   applied, but in example #2 the setting will not be read and a default will be applied.
+
+   Example #1:
+   ```yaml
+   pid_file: DATADIR/homeserver.pid
+   ```
+   Example #2:
+   ```yaml
+   #pid_file: DATADIR/homeserver.pid
+   ```
+* Indentation matters! The indentation before a setting
+  will determine whether a given setting is read as part of another
+  setting, or considered on its own. Thus, in example #1, the `enabled` setting
+  is read as a sub-option of the `presence` setting, and will be properly applied.
+
+  However, the lack of indentation before the `enabled` setting in example #2 means
+  that when reading the config, Synapse will consider both `presence` and `enabled` as
+  different settings. In this case, `presence` has no value, and thus a default applied, and `enabled`
+  is an option that Synapse doesn't recognize and thus ignores.
+
+  Example #1:
+  ```yaml
+  presence:
+    enabled: false
+  ```
+  Example #2:
+  ```yaml
+  presence:
+  enabled: false
+  ```
+  In this manual, all top-level settings (ones with no indentation) are identified
+  at the beginning of their section (i.e. "### `example_setting`") and
+  the sub-options, if any, are identified and listed in the body of the section.
+  In addition, each setting has an example of its usage, with the proper indentation
+  shown.
