+#### Using readonly chat url
+
+You can use the «share chat link» feature (see above) to generate an url to your chat.
+Check the «readonly» checkbox in the modal.
+Then use this link as a «web browser source» in OBS.
+
+Note: you can customize colors. This is undocumented yet, but you can try this:
+in the modal, check «use curent theme colors», then you can try to manually change color values in the url.
+You must use valid CSS color values, and they must be properly url encoded.
+
+#### Using Matterbridge
 
 Here is a tutorial to use Matterbridge with the plugin: <https://gitlab.com/refrac/obs-matterbridge-overlay/-/blob/master/documentation/peertube.md>
