-Documentation in four modes of information delivery
-===================================================
-
-.. rst-class:: intro
-Wagtail documentation is written in four modes of information delivery.
-Each type of information delivery has a purpose and targets a specific audience.
-
-  * :ref:`doc-style-tutorial`, learning-oriented
-  * :ref:`doc-style-how-to-guide`, goal-oriented
-  * :ref:`doc-style-reference`, information-oriented
-  * :ref:`doc-style-explanation`, understanding-oriented

-
-Write in style
---------------
-
-Each page of the Wagtail documentation should be written in **one** mode of information delivery.
-
-Mixing types of information delivery on a single page is bad style.
-These pages are are confusing to read, and harder to understand.
-It is best to split documents that mix the types of information delivery.
-Add links to the first section of each document to cross reference the same topic.
-
-Writing documentation in a specific mode  will help our users to understand, and quickly find what they are looking for.
-
-.. _doc-style-tutorial:
-
-Tutorial
---------
-
-Tutorials are designed to be a **learning-oriented** resource that take
-newcomers by the hand and guide them through a specific topic. To facilitate effective
-learning, tutorials provide examples to illustrate the subjects they cover.
-
-They may not necessarily follow best-practices by the letter. They are
-designed to make it easier to get started.

-.. _doc-style-reference:
-
-Reference
----------
-
-A reference is well structured and allows the reader to find information about a specific
-topic. They should be short and to the point. Reference material is **information-oriented**.

-
-Explanation
