+User Guide
+__________
+
+
+Core guides
+-----------
+
+These user guides provide detailed explanation of some of the core
+concepts in HoloViews:
+
+* `Annotating your Data <Annotating_Data.html>`_
+  How to wrap your data in Element and annotate it with additional
+  metadata to explore and visualize it effectively.
+
+* `Composition of Elements <Composing_Elements.html>`_
+  Composing your wrapped data into ``Overlay`` and ``Layout``
+  collections with the ``+`` and ``*`` operators.
+
+* `Customizing Plots <Customizing_Plots.html>`_
+  Applying plot, style and normalization options to control the look
+  and feel of the plotting.
+
+* `Dimensioned Containers <Dimensioned_Containers.html>`_
+  Declaring multi-dimensional containers to animate and facet your
+  data flexibly. Learn about ``HoloMap``, ``NdOverlay``, ``GridSpace``
+  and ``NdLayout`` types and how to use them effectively with the
+  corresponding ``.layout``, ``.overlay`` and ``.grid`` method.
+
+* `Building Composite Objects <Building_Composite_Objects.html>`_
+  How to build and work with complex composite objects.
+
+* `Live Data <Live_Data.html>`_
+  Introducing ``DynamicMap`` to lazily declare data and generate
+  complex interactive visualizations.
+
+* `Tabular Datasets <Tabular_Datasets.html>`_
+  Loading and wrapping tabular datasets in HoloViews using NumPy,
+  pandas and dask and flexibly exploring the dataset using selection,
+  grouping and aggregation.
+
+* `Gridded Datasets <Gridded_Datasets.html>`_
+  Loading and wrapping gridded dataset in HoloViews using NumPy and
+  XArray to flexibly explore and visualize labelled n-dimensional
+  arrays.
+
+* `Indexing and Selecting Data <Indexing_and_Selecting_Data.html>`_
+  Effectively indexing and selecting subsets of the data on the
+  different HoloViews datastructures.
+
+* `Transforming Elements <Transforming_Elements.html>`_
+  Applying and declaring ``Operations`` that transform your allowing
+  you to define the building blocks of a data analysis pipeline and
+  quickly explore and visualize the effect of different parameters on
+  your data.
+
+* `Responding to Events <Responding_to_Events.html>`_
+  Effectively using ``Streams`` to dynamically control and drive your
+  visualizations by responding to user defined events such as custom
+  widgets or from the commandline or notebook.
+
+* `Custom Interactivity <Custom_Interactivity.html>`_
+  Using linked ``Streams`` to respond to events generated by
+  interacting with a bokeh plot, e.g. by responding to mouse position,
+  mouse taps, selections or the current axis range.
+
+* `Data Transformation Pipelines <Data_Pipelines.html>`_
+  Chaining different operations to build complex and lazy data
+  analysis pipelines, which can drive interactive plots in a notebook
+  or in a deployed dashboard.
+
+* `Working with large data <Large_Data.html>`_
+  Leveraging datashader support in HoloViews to effectively and
+  interactively explore and visualize millions or even billions of
+  datapoints.
+
+
+Supplementary guides
+--------------------
+
+These guides provide detail about specific additional features in HoloViews:
+
+* `Plotting with Bokeh <Plotting_with_Bokeh.html>`_
+  The basics of plotting with bokeh including details about plot tools
+  and backend specific styling options and working with bokeh models
+  more directly.
+
+* `Deploying Bokeh Apps <Deploying_Bokeh_Apps.html>`_
+  Instructions on how to declare and deploy bokeh apps using HoloViews
+  in various scenarios, e.g. from scripts, from the commandline and
+  within the notebook.
+
+* `Plotting with matplotlib <Plotting_with_Matplotlib.html>`_
+  The basics of plotting with matplotlib highlighting core differences
+  in styling and controlling the layout of matplotlib figures.
+
+* `Plotting with plotly <Plotting_with_Plotly.html>`_
+  The basics of plotting with plotly focusing on 3D plotting, one of
+  the main strengths of plotly.
+
+* `Working with renderers and plots <Plots_and_Renderers.html>`_
+  Using HoloViews Renderer and Plot classes directly to access and
+  manipulate your visualizations directly.
+
+* `Exporting and Archiving <Exporting_and_Archiving.html>`_
+  Using HoloViews to archive both your data and visualization from the
+  notebook.
+
+* `Continuous Coordinates <Continuous_Coordinates.html>`_ Details on
+  how continuous coordinates are handled in HoloViews specifically
+  focusing on the difference between ``Image`` and other ``Raster`` types.
