+## synapse-auto-compressor support
+
+Thanks to [Aine](https://gitlab.com/etke.cc) of [etke.cc](https://etke.cc/), the playbook can now set up [rust-synapse-compress-state](https://github.com/matrix-org/rust-synapse-compress-state)'s `synapse_auto_compressor` tool to run periodically.
+
+If enabled, `synapse_auto_compressor` runs on a schedule and compresses your Synapse database's `state_groups` table. It was possible to run `rust-synapse-compress-state` manually via the playbook even before - see [Compressing state with rust-synapse-compress-state](docs/maintenance-synapse.md#compressing-state-with-rust-synapse-compress-state). However, using `synapse_auto_compressor` is better, because:
+
+- it runs on a more up-to-date version of `rust-synapse-compress-state`
+- it's a set-it-and-forget-it tool that you can enable and never have to deal with manual compression anymore
+
+This tool needs to be enabled manually, for now. In the future, we're considering enabling it by default for all Synapse installations.
+
+See our [Setting up synapse-auto-compressor](docs/configuring-playbook-synapse-auto-compressor.md) documentation to get started.

+# Setting up synapse_auto_compressor
+
+The playbook can install and configure [synapse_auto_compressor](https://github.com/matrix-org/rust-synapse-compress-state/#automated-tool-synapse_auto_compressor) for you.
+
+It's a CLI tool that automatically compresses Synapse's `state_groups` database table in the background.
+
+See the project's [documentation](https://github.com/matrix-org/rust-synapse-compress-state/#automated-tool-synapse_auto_compressor) to learn what it does and why it might be useful to you.
+
+
+## Adjusting the playbook configuration
+
+Add the following configuration to your `inventory/host_vars/matrix.DOMAIN/vars.yml` file:
+
+```yaml
+matrix_synapse_auto_compressor_enabled: true
+```
+
+
+## Installing
+
+After configuring the playbook, run the [installation](installing.md) command again:
+
+```
+ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,start
+```
+
+
+## Usage
+
+After installation, `synapse_auto_compressor` will run automatically every day at `00:00:00` (as defined in `matrix_synapse_auto_compressor_calendar` by default).
+
+## Manually start the tool
+
+For testing your setup it can be helpful to not wait until 00:00. If you want to run the tool immediately, log onto the server
+and run `systemctl start matrix-synapse-auto-compressor`. Running this command will not return control to your terminal until the compression run is done, which may take a long time.
+Consider using [tmux](https://en.wikipedia.org/wiki/Tmux) if your SSH connection is unstable.
