+# Media repository callbacks
+
+Media repository callbacks allow module developers to customise the behaviour of the
+media repository on a per user basis. Media repository callbacks can be registered
+using the module API's `register_media_repository_callbacks` method.
+
+The available media repository callbacks are:
+
+### `get_media_config_for_user`
+
+_First introduced in Synapse v1.132.0_
+
+```python
+async def get_media_config_for_user(user_id: str) -> Optional[JsonDict]
+```
+
+**<span style="color:red">
+Caution: This callback is currently experimental . The method signature or behaviour
+may change without notice.
+</span>**
+
+Called when processing a request from a client for the
+[media config endpoint](https://spec.matrix.org/latest/client-server-api/#get_matrixclientv1mediaconfig).
+
+The arguments passed to this callback are:
+
+* `user_id`: The Matrix user ID of the user (e.g. `@alice:example.com`) making the request.
+
+If the callback returns a dictionary then it will be used as the body of the response to the
+client.
+
+If multiple modules implement this callback, they will be considered in order. If a
+callback returns `None`, Synapse falls through to the next one. The value of the first
+callback that does not return `None` will be used. If this happens, Synapse will not call
+any of the subsequent implementations of this callback.
+
+If no module returns a non-`None` value then the default media config will be returned.
+

+**<span style="color:red">

+may change without notice.
+</span>**
+
+Called before media is accepted for upload from a user, in case the module needs to
+enforce a different limit for the particular user.
+
+The arguments passed to this callback are:
+
+* `user_id`: The Matrix user ID of the user (e.g. `@alice:example.com`) making the request.
+* `size`: The size in bytes of media that is being requested to upload.
+
+If the module returns `False`, the current request will be denied with the error code
+`M_TOO_LARGE` and the HTTP status code 413.
+
+If multiple modules implement this callback, they will be considered in order. If a callback
+returns `True`, Synapse falls through to the next one. The value of the first callback that
+returns `False` will be used. If this happens, Synapse will not call any of the subsequent
+implementations of this callback.

+# Ratelimit callbacks
+
+Ratelimit callbacks allow module developers to override ratelimit settings dynamically whilst
+Synapse is running. Ratelimit callbacks can be registered using the module API's
+`register_ratelimit_callbacks` method.

+
+**<span style="color:red">
+Caution: This callback is currently experimental . The method signature or behaviour
+may change without notice.
+</span>**
+
+Called when constructing a ratelimiter of a particular type for a user. The module can
+return a `messages_per_second` and `burst_count` to be used, or `None` if
+the default settings are adequate. The user is represented by their Matrix user ID
+(e.g. `@alice:example.com`). The limiter name is usually taken from the `RatelimitSettings` key
+value.
+
+The limiters that are currently supported are:
+
+- `rc_invites.per_room`
+- `rc_invites.per_user`
+- `rc_invites.per_issuer`
+
+The `RatelimitOverride` return type has the following fields:
+
+- `per_second: float`. The number of actions that can be performed in a second. `0.0` means that ratelimiting is disabled.
+- `burst_count: int`. The number of actions that can be performed before being limited.
+
+If multiple modules implement this callback, they will be considered in order. If a
+callback returns `None`, Synapse falls through to the next one. The value of the first
+callback that does not return `None` will be used. If this happens, Synapse will not call
+any of the subsequent implementations of this callback. If no module returns a non-`None` value
+then the default settings will be used.

+
+# 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.
