+The scope is _not_ the current indentation level! Instead, it is the
+indentation level where variables or functions are accessible, as in [Wikipedia Scope (Computer Science)](<https://en.wikipedia.org/wiki/Scope_(computer_science)>). This depends
+on the language you are writing. For more information, see `:help ibl.config.scope`.
+
 The start and end of scope uses underline, so to achieve the best result you
 might need to tweak the underline position. In Kitty terminal for example you
 can do that with [modify_font](https://sw.kovidgoyal.net/kitty/conf/#opt-kitty.modify_font)
