+## Customizing the Queue UI
+
+The Matchmaker server allows for custom HTML UI to be displayed. In order to create a custom queue UI template:
+
+1. Duplicate the `Matchmaker/html/sample` directory as `Matchmaker/html/custom`.
+2. Edit `Matchmaker/html/custom/queue/queue.html` as needed.
+
+It is required to keep the same directory struture and file names for the template (`.html`) files. The Matchmaker server will prefer the `custom` directory over `sample`. The `custom` directory always needs to contain all templates from the `sample` directory.
+
+The `custom` directory can contain additional files, which may be referenced in the template files with a path relative to `Matchmaker/html/custom`. For example, an image located as `Matchmaker/html/custom/images/1.png` could be referenced as `<img src="/images/1.png" alt="">` in a template (`.html`) file.

+# Pixel Streaming Matchmaker
+
+Instead of having all users connect to the same stream, you may want each person to end up in their own interactive experiences. To do this, you can run a separate stack of Pixel Streaming components for each user, and direct each user to a separate Signaling and Web Server to start a connection.
+
+You can set up each stack of Pixel Streaming components on a separate host, or you can put more than one stack on the same host as long as you configure the port settings for the components within each stack so that they all communicate over different ports. See the Pixel Streaming Reference for details on these port settings.
+
+To help set up this kind of configuration, the Pixel Streaming system can use a **matchmaker** server that tracks which Signaling and Web Servers are available, and whether they are being used by a client connection.
+
