 ## Configuration
 
-`kbs2-snip` reads the `commands.ext.snip.matcher` setting in the configuration
+`kbs2-snip` reads the `commands.ext.snip.chooser` setting in the configuration
 file to determine which fuzzy finder to use.
 
 For example:
 
 ```toml
 [commands.snip]
-matcher = "fzf"
+chooser = "fzf"
 ```
 
 ...will cause `kbs2-snip` to use [`fzf`](https://github.com/junegunn/fzf).
