-The usages and examples are written in TypeScript, but the library can also be used in plain JavaScript after removing the type annotations (and changing the imports if you are using CommonJS).  
-If the usage section contains multiple definitions of the function, each occurrence represents an overload and you can choose which one you want to use.  
+The usages and examples are written in TypeScript and use ESM import syntax, but the library can also be used in plain JavaScript after removing the type annotations (and changing the imports if you are using CommonJS or the global declaration).  
+If the usage section contains multiple usages of the function, each occurrence represents an overload and you can choose which one you want to use.  
   
 Some features require the `@run-at` or `@grant` directives to be tweaked in the userscript header or have other requirements.  
 Their documentation will contain a section marked by a warning emoji (⚠️) that will go into more detail.
