+Parameter Trees
+===============
+
+Parameter trees are a system for handling hierarchies of parameters while automatically generating one or more GUIs to display and interact with the parameters.
+This feature is commonly seen, for example, in user interface design applications which display a list of editable properties for each widget.
+Parameters generally have a name, a data type (int, float, string, color, etc), and a value matching the data type. Parameters may be grouped and nested
+to form hierarchies and may be subclassed to provide custom behavior and display widgets.
+
+Pyqtgraph's parameter tree system works similarly to the model-view architecture used by some components of Qt: Parameters are purely data-handling classes
+that exist independent of any graphical interface. A ParameterTree is a widget that automatically generates a graphical interface which represents
+the state of a haierarchy of Parameter objects and allows the user to edit the values within that hierarchy. This separation of data (model) and graphical
+interface (view) allows the same data to be represented multiple times and in a variety of different ways.

 The parameter tree system provides a widget displaying a tree of modifiable values similar to those used in most GUI editor applications. This allows a large number of variables to be controlled by the user with relatively little programming effort. The system also provides separation between the data being controlled and the user interface controlling it (model/view architecture). Parameters may be grouped/nested to any depth and custom parameter types can be built by subclassing from Parameter and ParameterItem.
