+The intention of this stage is to write received messages to a different redis/[valkey](https://valkey.io/) instance. This means data created by SAE can be transfered to a backend.
+It transparently forwards all messages it receives, regardless of their type, to the configured Redis instance.
+If the configuration option `remove_frame_data` is set and the message sucessfully parses as a `SaeMessage`, all image data will be removed from the frame before forwarding the message.
 
 The following features are planned:
 - Aggregate all messages into a single output stream, therefore leaving it to the receiver to filter (this should be feasible, because messages without frame data are magnitudes smaller, see below)
-- Remove all frame data for privacy and volume reasons
