+    fig
+        Figure object or dict representing a figure
+    skip
+        A collection of names of properties to skip when moving properties to
+        the template. Defaults to ('title', 'text') so that the text
+        of figure titles, axis titles, and annotations does not become part of
+        the template
+
+    Examples
+    --------
+    Imports
+    >>> import plotly.graph_objs as go
+    >>> import plotly.io as pio
+
+    Construct a figure with large courier text
+    >>> fig = go.Figure(layout={'title': 'Figure Title',
+    ...                         'font': {'size': 20, 'family': 'Courier'}})
+    >>> fig
+    Figure({
+        'data': [],
+        'layout': {'title': 'Figure Title',
+                   'font': {'family': 'Courier', 'size': 20}}
+    })
+
+    Convert to a figure with a template. Note how the 'font' properties have
+    been moved into the template property.
+    >>> templated_fig = pio.to_templated(fig)
+    >>> templated_fig
+    Figure({
+        'data': [],
+        'layout': {'title': 'Figure Title',
+                   'template': {'layout': {'font': {'family': 'Courier',
+                                                    'size': 20}}}}
+    })
+
+    Next create a new figure with this template
+
+    >>> fig2 = go.Figure(layout={
+    ...     'title': 'Figure 2 Title',
+    ...     'template': templated_fig.layout.template})
+    >>> fig2
+    Figure({
+        'data': [],
+        'layout': {'title': 'Figure 2 Title',
+                   'template': {'layout': {'font': {'family': 'Courier',
+                                                    'size': 20}}}}
+    })
+
+    The default font in fig2 will now be size 20 Courier.
+
+    Next, register as a named template...
+    >>> pio.templates['large_courier'] = templated_fig.layout.template
+
+    and specify this template by name when constructing a figure.
+
+    >>> go.Figure(layout={
+    ...     'title': 'Figure 3 Title',
+    ...     'template': 'large_courier'})
+    Figure({
+        'data': [],
+        'layout': {'title': 'Figure 3 Title',
+                   'template': {'layout': {'font': {'family': 'Courier',
+                                                    'size': 20}}}}
+    })
+
+    Finally, set this as the default template to be applied to all new figures
+
+    >>> pio.templates.default = 'large_courier'
+    >>> go.Figure(layout={'title': 'Figure 4 Title'})
+    Figure({
+        'data': [],
+        'layout': {'title': 'Figure 4 Title',
+                   'template': {'layout': {'font': {'family': 'Courier',
+                                                    'size': 20}}}}
+    })

-                Templates can be created from existing plots
