+# `finallycoffee.matrix.cinny` ansible role
+
+> [!WARNING]
+> This role is a WIP and not yet usable
+
+## Supported deployment methods
+
+Set your `deployment_method` to:
+
+- [`docker` (docs)](docs/docker.md) (current default)
+- `podman`
+- [`nginx` (docs)](docs/nginx.md)
+- [`tarball` (docs)](docs/tarball.md)
+
+Not yet implemented but planned:
+
+- `apache2`
+- `caddy`
+
+## Configuration
+
+All cinny `config.json` configuration keys are available as a snake-cased ansible variable:
+- `cinny_config_homeserver_list`
+- `cinny_config_allow_custom_homeservers`
+- [...]
+
+If you want to provide structured configuration directly, you can either provide additional configuration in `cinny_config` or overwrite all existing defaults by setting `cinny_config_complete`.
+
+To ensure cinny is removed from the system, set `cinny_state` to `absent` (default is `present`).
