+
+## ⚠️ Important: Changing Font Awesome Version
+
+If you update to a different Font Awesome version, you must **update all SVG
+files** and **comments inside the files** to reflect the new version number and
+licensing URL accordingly. For example:
+
+* Original:
+```xml
+<!--!Font Awesome Free 6.7.2 by @fontawesome - https://fontawesome.com License - https://fontawesome.com/license/free Copyright 2025 Fonticons, Inc.-->
+```
+* Updated:
+```xml
+<!--!Font Awesome Free X.Y.Z by @fontawesome - https://fontawesome.com License - https://fontawesome.com/license/free Copyright YYYY Fonticons, Inc.-->
+```
+
+## Adding a new icon
+
+1. Use only [Font Awesome Free Icons](https://fontawesome.com/icons).
+2. Save the icon as a .svg file in this directory.
+3. Include the following attribution comment at the top of the file (do not change it):
+```xml
+<!--!Font Awesome Free 6.7.2 by @fontawesome - https://fontawesome.com License - https://fontawesome.com/license/free Copyright 2025 Fonticons, Inc.-->
+```
+4. Right before the `<path>` element, add the following metadata comment, using the correct values:
+```xml
+<!--
+  Icon Name: [icon-name]
+  Icon Family: [classic | sharp | brands | etc.]
+  Icon Style: [solid | regular | light | thin | duotone | etc.]
+-->
+```
+
