+# Icons & Colours
+
+> **Note:** Starting with Thunderbird 128 / Add-on Version 0.2.0 it is not possible to set custom icons. As an alternative, it is possible to customise the badge background. See #1 for more information.
+
+This is a growing database of URLs to Icons and colours of more or less commonly used web apps.
+
+The list will be sorted alphabetically and you are encouraged to use the search functionality of your browser.
+
+If you would like to see more items here, notice an icon URL on longer working or a changed colour, feel free to open an [issue](https://git.mmk2410.org/mmk2410/SpaceApper/src/branch/main/README.md#issues-and-code-contribution).
