+   extension installed, then visit

+3. Click install on the top left
+
+## Notes
+
+- Themes modern Atlassian Cloud (Jira, Confluence, ...) by recolouring the
+  Atlassian Design System (ADS) `--ds-*` tokens.
+- The **Light Variant** is applied when Atlassian is in light mode and the
+  **Dark Variant** when it is in dark mode (set via your Atlassian profile →
+  Theme). "Match browser" is respected.
+- Adapted from the Atlassian Catppuccin userstyle.
