 ### Streaming Mode
 
-Three streaming modes are currently supported: `MPEG-TS` (Transport Stream), `HLS Direct` (HTTP Live Streaming Direct) and `HLS Hybrid` (HTTP Live Streaming Hybrid).
+Four streaming modes are currently supported: `MPEG-TS` (Transport Stream), `HLS Direct` (HTTP Live Streaming Direct), `HLS Hybrid` (HTTP Live Streaming Hybrid) and `HLS Segmenter` (HTTP Live Streaming Segmenter).
 
 * `MPEG-TS` transcodes content and supports watermarks, though some clients will have issues at program boundaries
 * `HLS Direct` does not transcode content and can perform better on low power systems, but does not support watermarks and some clients will have issues at program boundaries
 * `HLS Hybrid` transcodes content and supports watermarks, and can perform very well at program boundaries with some clients
+* `HLS Segmenter` is currently *experimental*, and is the only "proper" HLS mode. It transcodes content, supports watermarks and offers the best performance at program boundaries.
