 ## Usage
 
 ### Basic Usage
+
 - Press your toggle key to start; press again to stop.
 - Audio is captured via PipeWire; the pipeline enters `transcribing` after the first frame.
 - On toggle‑off during `transcribing`, an `inject` action is sent. Injection is currently simulated (no clipboard paste yet).

 ### State Machine
+
 The pipeline operates with these states:
+
 - idle → recording → transcribing → injecting → idle
 
 ### IPC Protocol
+
 Single-character commands over Unix socket:
+
 - `t` - Toggle recording
 - `s` - Get status
 - `v` - Get protocol version
 - `q` - Quit daemon
 
 ### Running in Development

-## Recent changes
-
-- Migrated runtime state from the daemon to the pipeline. The daemon now just starts/stops the pipeline and proxies status.
-- Introduced an action channel for control (`inject`), enabling toggle‑to‑inject behavior while transcribing.
-- Implemented PipeWire recording via `pw-record` with bounded channels and basic backpressure logging.
-- Desktop notifications wired for start/end/abort (transcribing notification hook available).
-- Added CLI commands: `serve`, `toggle`, `status`, `version`, `stop`.
-
 ## Direction / Roadmap
 
 - ASR integration: start with a cloud streaming backend; add a local backend later.
