+---
+--- A Perl language server. It can be installed via npm:
+---
+--- ```sh
+--- npm i -g perlnavigator-server
+--- ```
+---
+--- At minimum, you will need `perl` in your path. If you want to use a non-standard `perl` you will need to set your configuration like so:
+--- ```lua
+--- settings = {
+---   perlnavigator = {
+---     perlPath = '/some/odd/location/my-perl'
+---   }
+--- }
+--- ```
+---
+--- The `contributes.configuration.properties` section of `perlnavigator`'s `package.json` has all available configuration settings. All
+--- settings have a reasonable default, but, at minimum, you may want to point `perlnavigator` at your `perltidy` and `perlcritic` configurations.
