+### IMPORTANT: Disabling Rango on Some Browsers
+
+Once **rango-talon** has been added to your talon user folder, Rango will be
+active for all your browsers. If you haven't installed the extension itself in a
+specific browser, it's better to disable Rango for that browser to avoid
+unexpected behavior. The best way to do this is to activate the tag
+`user.rango_disabled` for that browser. For example, if you want to disable
+Rango in Brave and Chrome, you could have a _.talon_ file with the following
+contents anywhere in your talon user folder.
+
+```talon
+app: brave
+app: chrome
+-
+tag(): user.rango_disabled
