 ### Properties
 
-`viewOnly`
-  - Is a `boolean` indicating if any events (e.g. key presses or mouse
-    movement) should be prevented from being sent to the server.
-    Disabled by default.
-
-`focusOnClick`
-  - Is a `boolean` indicating if keyboard focus should automatically be
-    moved to the remote session when a `mousedown` or `touchstart`
-    event is received. Enabled by default.
-
-`clipViewport`
-  - Is a `boolean` indicating if the remote session should be clipped
-    to its container. When disabled scrollbars will be shown to handle
-    the resulting overflow. Disabled by default.
-
-`dragViewport`
-  - Is a `boolean` indicating if mouse events should control the
-    relative position of a clipped remote session. Only relevant if
-    `clipViewport` is enabled. Disabled by default.
-
-`scaleViewport`
-  - Is a `boolean` indicating if the remote session should be scaled
-    locally so it fits its container. When disabled it will be centered
-    if the remote session is smaller than its container, or handled
-    according to `clipViewport` if it is larger. Disabled by default.
-
-`resizeSession`
-  - Is a `boolean` indicating if a request to resize the remote session
-    should be sent whenever the container changes dimensions. Disabled
-    by default.
-
-`showDotCursor`
-  - Is a `boolean` indicating whether a dot cursor should be shown
-    instead of a zero-sized or fully-transparent cursor if the server
-    sets such invisible cursor. Disabled by default.
-
 `background`
-  - Is a valid CSS [background](https://developer.mozilla.org/en-US/docs/Web/CSS/background)
-    style value indicating which background style should be applied
-    to the element containing the remote session screen. The default value is `rgb(40, 40, 40)`

+    background style should be applied to the element containing the
+    remote session screen. The default value is `rgb(40, 40, 40)` (solid
+    gray color).
 
-`qualityLevel`
-  - Is an `int` in range `[0-9]` controlling the desired JPEG quality.
-    Value `0` implies low quality and `9` implies high quality.
-    Default value is `6`.
-
-`compressionLevel`
-  - Is an `int` in range `[0-9]` controlling the desired compression
-    level. Value `0` means no compression. Level 1 uses a minimum of CPU
-    resources and achieves weak compression ratios, while level 9 offers
-    best compression but is slow in terms of CPU consumption on the server
-    side. Use high levels with very slow network connections.
-    Default value is `2`.
