+How To Use Sections Effectively
+*******************************
+
+You can nest sections in the topic as needed to structure it and break it into discrete parts.
+
+Copy the Topic and Section Structure below as needed.
+
+.. code-block:: RST
+
+   Topic Title
+   ###########
+
+   Introduce the topic
+
+   If this is a long topic with multiple sections, use the **contents** directive below:
+
+   .. contents:: Contents
+      :depth: 1
+      :local:
+
+   Section 1
+   *********
+
+   Introduce Section One

+   Subsection 1
+   ++++++++++++

+Add a Substitution
+******************
+
+In RST, a *substitution* serves as a variable which you can set a value for once, then use repeatedly. This is useful for words or phrases that are used often, as it enables you to edit the value once and change it everywhere.
+
+You also need to use substitutions for inline images, as explained below.
+
+Substitutions are all kept in the source/substitutions.txt file in the documentation project on GitHub.
+
+Copy the format for the substitution as needed.
+
+.. code-block:: RST
+
+  .. |variable name| replace:: value
+
+  .. |Platform name| replace:: Open edX
+
+You then add the *variable name* inline in the topic.
+
+.. code-block:: RST
+
+  A line of text with an |variable name| inserted.
+
+
+Add a Sidebar
+*************
+
+You can add any content in a sidebar. Open edX documentation uses sidebars for image thumbnails, videos, and other notes.
+
+The sidebar must come directly after a heading.
+
+Copy this codeblock to add a new sidebar topic.
+
+.. code-block:: RST
+
+  .. sidebar:: Sample Sidebar
+
+    Any content, typically an image, video, or note.
+
+Add an Image to a Topic
+***********************
+
+You can add an image on its separate line, inline, or in a sidebar.
+
+You can also add an image directly or add a thumbnail of a larger image, which, when clicked on, will open the full image.
+
+You must save images in the ``source/_images`` directory before adding a reference to it in a topic. 
+
+Add an Image on its Own Line
+============================
+
+Copy this codeblock to an image on its own line.
+
+.. code-block:: RST
+
+  Line of content, followed by a line with an image.
+
+  .. image:: /_images/image-file-name
+
+  Or, a line of content, followed by a clickable thumbnail of a large image.
+
+  .. thumbnail:: /_images/image-file-name
+
+Add an Image Inline
+===================
+
+To add an image inline, you must first create a substitution for the image in the substitutions.txt file.
+
+Copy the format for the substitution as needed.
+
+.. code-block:: RST
+
+  .. |variable name| image:: /_images/image-file-name
+
+You then add the *variable name* inline in the topic.
+
+.. code-block:: RST
+
+  A line of text with an |variable name| inserted.
+
+Add a Thumbnail in a Sidebar
+============================
+
+You can add a thumbnail in a sidebar, a common practice for How-to topics.
+
+The sidebar must come directly after a heading.
+
+Copy this codeblock to add a new sidebar with a thumbnail.
+
+.. code-block:: RST
+
+  .. sidebar:: Sample Sidebar with a thumbnail
+
+    .. thumbnail:: _images/image-file-name
