# reStructuredText files#

In addition to writing your content in Markdown, Jupyter Book also supports writing content in reStructuredText, another markup language that is common in the Python documentation community.

Warning

Writing content in reStructuredText is only recommended for users who are already familiar with it. For others, we recommend using MyST Markdown, which has all of the same features of rST and Sphinx, but with a Markdown flavour.

Because Jupyter Book uses Sphinx under the hood, any document that is written in rST for the Sphinx ecosystem should also work with Jupyter Book. This is particularly useful if you’ve already got a significant amount of documentation written in rST and you’d like to try it out with Jupyter Book.

For more information on writing content with reStructuredText, we recommend reading the Sphinx rST documentation.

## Including reStructuredText in Markdown#

To insert rST into Markdown, you can use the eval-rst directive:

{eval-rst}
.. note::

A note written in reStructuredText.

.. include:: ./include-rst.rst



Note

A note written in reStructuredText.
