+## Accessible Themes
+
+Much of the accessibility of a website is dependent on how specific HTML tags and
+attributes are used, thus falls largely into the realm of Drupal Themes. The
+[Olivero](https://www.drupal.org/docs/core-modules-and-themes/core-themes/olivero) theme
+and the [Claro](https://www.drupal.org/docs/core-modules-and-themes/core-themes/claro-theme)
+ admin theme were designed by the Drupal community with accessibility
+as a guiding principle.
+
+## Automatic alt-text
+
+When creating image media, alt-text is a required attribute. An Islandora function
+currently automatically populates the alt-text, if that media is the "media of" a node,
+with the respective node's title.
+
+This is not considered good accessibility as the node's title will likely be already
+on the page, and it doesn't add anything to describing the image itself. Please fill
+out the alt text with something meaningful when adding image content to Islandora.
