+Adding new documentation
+------------------------
+
+Documentation can be added as a
+`sphinx-gallery <https://sphinx-gallery.github.io/stable/index.html>`_
+python file ('tutorials')
+or a
+`sphinx rst <https://sphinx-tutorial.readthedocs.io/step-1/>`_
+file (all other sections).
+
+To add a new tutorial, add your ``.py`` file to ``spikeinterface/examples``.
+Then, update the ``spikeinterface/doc/tutorials_custom_index.rst`` file
+to make a new card linking to the page and an optional image. See
+``tutorials_custom_index.rst`` header for more information.
+
+For other sections, write your documentation in ``.rst`` format and add
+the page to the appropriate ``index.rst`` file found in the relevant
+folder (e.g. ``how_to/index.rst``).

+.. This page provides a custom index to the 'Tutorials' page, rather than the default sphinx-gallery
+.. generated page. The benefits of this are flexibility in design and inclusion of non-sphinx files in the index.
+..
+.. To update this index with a new documentation page
+.. 1) Copy the grid-item-card and associated ".. raw:: html" section.
+.. 2) change :link: to a link to your page. If this is an `.rst` file, point to the rst file directly.
+..    If it is a sphinx-gallery generated file, format the path as separated by underscore and prefix `sphx_glr`,
+..    pointing to the .py file. e.g. `tutorials/my/page.py` -> `sphx_glr_tutorials_my_page.py
+.. 3) Change :img-top: to point to the thumbnail image of your choosing. You can point to images generated
+..    in the sphinx gallery page if you wish.
+.. 4) In the `html` section, change the `default-title` to your pages title and `hover-content` to the subtitle.
