 You can add additional `Sphinx extensions`_ to your Sphinx build to make use of custom reStructuredText directives and roles.
-To add a new extension, append to the ``extensions`` list:
-

-
-   from documenteer.conf.technote import *

-   extensions.extend(["sphinx-click"])

-Remember that if an additional package needs to be installed, add that dependency to the technote's :file:`requirements.txt` file.

+##############################
+Sphinx extensions in technotes
+##############################
+
+Technotes include Sphinx extensions that provide additional features, like diagrams-as-code.
+This page explains what extensions are included by default in Rubin technotes, and how to add additional extensions to your own technote as needed.
+
+.. _technote-default-extensions:
+
+Default extensions
+==================
+
+These extensions are included and pre-configured in all technotes:
+
+:doc:`documenteer.ext.jira </sphinx-extensions/jira-reference>`
+   This extension provides roles for linking to Jira issues.
+
+:doc:`documenteer.ext.lsstdocushare </sphinx-extensions/docushare-reference>`
+   This extension provides roles for linking to Rubin Observatory documents based on their handle.
+
+:doc:`documenteer.ext.remotecodeblock </sphinx-extensions/remote-code-block>`
+   This extension allows you to include a literal code block where the source for that code block is available at an web URL.
+
+:doc:`documenteer.ext.bibtex </sphinx-extensions/lsst-pybtex-style>`
+   This extension works with the `sphinxcontrib-bibtex`_ extension to handle the BibTeX entires in https://github.com/lsst/lsst-texmf.
+
+:doc:`documenteer.ext.githubbibcache </sphinx-extensions/githubbibcache>`
+  This extension automatically downloads and caches the BibTeX files from https://github.com/lsst/lsst-texmf, for use with the `sphinxcontrib-bibtex`_ extension.
+
+`myst_parser`_
+   This extension allows you to use the MyST_ markup language (i.e., Markdown) in your technote.
+
+`sphinx.ext.intersphinx`_
+   This extension allows you to link to other Sphinx projects, including other Rubin technotes and user guides and many open-source projects like Astropy and Numpy.
+
+`sphinxcontrib-bibtex`_
+   This extension allow you to include a BibTeX-based bibliography in your technote.
+
+`sphinx-prompt`_
+   Sphinx-prompt lets you add a prompt to code blocks.
+   This is useful for showing what a user might type at an interactive terminal.
+
+`sphinxcontrib-mermaid`_
+   Mermaid is a diagrams-as-code tool that allows you to create flowcharts, sequence diagrams, entity relationship diagrams, and more.
+   See the Mermaid_ documentation for more information, and see the `sphinxcontrib-mermaid`_ documentation for Sphinx-specific usage.
+
+`sphinx-diagrams`_
+   The Diagrams extension allows you to make architectural diagrams from code.
+   This extension is particularly useful for describing Kubernetes application deployments.
+
+.. _technote-adding-extensions:
+
+Adding additional extensions
+============================
+
+If you know of a Sphinx extension that you would like to use with your technote, you can add it yourself.
+Here are the steps, using sphinxcontrib-mermaid_ as an example (this is already included in all technotes):
+
+1. Add the extension's Python package to :file:`requirements.txt` in the technote's repository.
+   This is the extension's PyPI package name, since technotes use pip to install build dependencies.
+
+   .. code-block:: text
+      :caption: requirements.txt
+      :emphasize-lines: 2
+
+      documenteer[technote]
+      sphinxcontrib-mermaid
+
+2. Add the extension to the :external+technote:ref:`technote.sphinx.extensions <toml-technote-sphinx-extensions>` array in :file:`technote.toml`.
+   Either append to the existing array, or create a new array if it doesn't exist in the TOML file yet.
+
+   .. code-block:: toml
+      :caption: technote.toml
+      :emphasize-lines: 2
+
+      [technote.sphinx]
+      extensions = ["sphinxcontrib.mermaid"]
+
+   .. tip::
+
+      The extension name is the Python package name, not the PyPI package name.
+      Look at the extension's installation documentation for the ``extensions`` variable to find the Python package name.
+
+   .. note::
+
+      User-defined extensions are always installed *in addition to* the default extensions.
+      You don't need to repeat the default extensions here.
+
+3. If the extension has configurations, you can set those in the :file:`conf.py` file.
+
+   .. code-block:: python
+      :caption: conf.py
+      :emphasize-lines: 3,4
+
+      from documenteer.conf.technote import *  # noqa: F401, F403
+
+      # -- Options for sphinxcontrib-mermaid -------------------------------------
+      mermaid_version = "8.9.2"
