+Markdown and RST supported by this forum
+========================================
+
+This is a cheat sheet for the *reStructuredText* dialect as implemented by
+Nim's documentation generator which has been reused for this forum.
+
+See also the
+`official RST cheat sheet <http://docutils.sourceforge.net/docs/user/rst/cheatsheet.txt>`_ 
+or the `quick reference <http://docutils.sourceforge.net/docs/user/rst/quickref.html>`_
+for further information.
+
+Elements of **markdown** are also supported.
+
+Inline elements
+---------------
+
+Ordinary text may contain *inline elements*:
+
+===============================   ============================================
+Plain text                        Result
+===============================   ============================================
+``*italic text*``                 *italic text*
+``**bold text**``                 **bold text**
+``***italic bold text***``        ***italic bold text***
+\``verbatim text \``              ``verbatim text``
+``http://docutils.sf.net/``       http://docutils.sf.net/
+``\\escape``                      \\escape
+===============================   ============================================
+
+Quoting other users can be done by prefixing their message with ``>``::
+
+  > Hello World
+
+  Hi!
+
+Which will result in:
+
+> Hello World
+
+Hi!
+
+Links
+-----
+
+Links are either direct URLs like ``https://nim-lang.org`` or written like
+this::
+  
+  `Nim <https://nim-lang.org>`_
+  
+Or like this::
+
+  `<https://nim-lang.org>`_
+
+
+Code blocks
+-----------
+
+The code blocks can be written in the same style as most common Markdown
+flavours::
+
+  ```nim
+    if x == "abc":
+      echo "xyz"
+  ```
+
+or using RST syntax::
+
+  .. code-block:: nim
+    
+    if x == "abc":
+      echo "xyz"
+
+Both are rendered as:
+
+.. code-block:: nim
+  
+  if x == "abc":
+    echo "xyz"
+
+
+Apart from Nim, the programming languages C, C++, Java and C# also
+have highlighting support.
+
+Literal blocks
+--------------
+
+These are introduced by '::' and a newline. The block is indicated by indentation:
+
+::
+  ::
+    if x == "abc":
+      echo "xyz"
+      
+The above is rendered as::
+
+    if x == "abc":
+      echo "xyz"
+
+
+
+Bullet lists
+------------
+
+Bullet lists look like this::
+
+  * Item 1
+  * Item 2 that
+    spans over multiple lines
+  * Item 3
+  * Item 4
+    - bullet lists may nest
+    - item 3b
+    - valid bullet characters are ``+``, ``*`` and ``-``
+
+The above rendered as:
+* Item 1
+* Item 2 that
+  spans over multiple lines
+* Item 3
+* Item 4
+  - bullet lists may nest
+  - item 3b
+  - valid bullet characters are ``+``, ``*`` and ``-``
+
+
+Enumerated lists
+----------------
+
+Enumerated lists are written like this::
+
+  1. This is the first item
+  2. This is the second item
+  3. Enumerators are arabic numbers,
+     single letters, or roman numerals
+  #. This item is auto-enumerated 
+
+They are rendered as:
+
+1. This is the first item
+2. This is the second item
+3. Enumerators are arabic numbers,
+   single letters, or roman numerals
+#. This item is auto-enumerated
+
+
+Tables
+------
+
+Only *simple tables* are supported. They are of the form::
+
+  ==================      ===============       ===================
+  header 1                header 2              header n
+  ==================      ===============       ===================
+  Cell 1                  Cell 2                Cell 3
+  Cell 4                  Cell 5; any           Cell 6
+                          cell that is
+                          not in column 1
+                          may span over
+                          multiple lines
+  Cell 7                  Cell 8                Cell 9
+  ==================      ===============       ===================
+
+This results in:
+==================      ===============       ===================
+header 1                header 2              header n
+==================      ===============       ===================
+Cell 1                  Cell 2                Cell 3
+Cell 4                  Cell 5; any           Cell 6
+                        cell that is
+                        not in column 1
+                        may span over
+                        multiple lines
+Cell 7                  Cell 8                Cell 9
+==================      ===============       ===================
+
+Images
+------
+
+Image embedding is supported. This includes GIFs as well as mp4 (for which a
+<video> tag will be automatically generated).
+
+For example:
+
+```
+.. image:: https://upload.wikimedia.org/wikipedia/commons/6/69/Dog_morphological_variation.png
+```
+
+Will render as:
+
+.. image:: https://upload.wikimedia.org/wikipedia/commons/6/69/Dog_morphological_variation.png
+
+And a GIF example:
+
+```
+.. image:: https://upload.wikimedia.org/wikipedia/commons/2/2c/Rotating_earth_%28large%29.gif
+```
+
+Will render as:
+
+.. image:: https://upload.wikimedia.org/wikipedia/commons/2/2c/Rotating_earth_%28large%29.gif
+
+You can also specify the size of the image:
+
+```
+.. image:: https://upload.wikimedia.org/wikipedia/commons/6/69/Dog_morphological_variation.png
+   :width: 40%
+```
+
+.. image:: https://upload.wikimedia.org/wikipedia/commons/6/69/Dog_morphological_variation.png
