 - `macroPackages` is an array of macros to use. By default, the plugin tries to choose a classical macro package using the file extension.
 
+- `macroPaths` is an array of additional paths to search for macros. The default value is empty, see `man groff_tmac` for further explanation about the search sequence.
+
 - `preprocessors` is an array of preprocessors to be used by **groff**. Common preprocessors are `tbl`, `pic` or `soelim`. It is empty by default.
 
 - `pattern` is the matcher used to determine the files to be transformed. It is used with **[minimatch][]**. The default value (`**/*.@(me|mm|ms|mom)`) matches all files ending with `.ms`, `.me`, `.mm` or `.mom` at any depth.
