+Forms in OpenLP are made up of two classes. One class holds all the graphical
+elements, like buttons and lists, and the other class holds all the functional
+code, like slots and loading and saving.
+
+The first class, commonly known as the **Dialog** class, is typically named
+``Ui_<name>Dialog``. It is a slightly modified version of the class that the
+``pyuic4`` command produces from Qt4's .ui file. Typical modifications will be
+converting most strings from "" to u'' and using OpenLP's ``translate()``
+function for translating strings.
+
+The second class, commonly known as the **Form** class, is typically named
+``<name>Form``. This class is the one which is instantiated and used. It uses
+dual inheritance to inherit from (usually) QtGui.QDialog and the Ui class
+mentioned above, like so::
+
+    class AuthorsForm(QtGui.QDialog, Ui_AuthorsDialog):
+
+        def __init__(self, parent=None):
+            QtGui.QDialog.__init__(self, parent)
+            self.setupUi(self)
+
+This allows OpenLP to use ``self.object`` for all the GUI elements while keeping
+them separate from the functionality, so that it is easier to recreate the GUI
+from the .ui files later if necessary.
