+    (description "PLS is a Perl language server that implements a subset of
+the Language Server Protocol for the Perl language.  Features currently
+implemented are:
+@itemize
+@item Go to definition (for packages, subroutines, and variables)
+@item Listing all symbols in a document
+@item Hovering to show documentation
+@item Signature help (showing parameters for a function as you type)
+@item Formatting
+@item Range formatting
+@item Auto-completion
+@item Syntax checking
+@item Linting (using perlcritic)
+@item Sorting imports
+@end itemize
+
+To use this language with Emacs, you can configure Eglot like so:
+@lisp
+(add-hook 'perl-mode-hook 'eglot-ensure)
+(setq eglot-server-programs '((perl-mode . (\"pls\"))))
+@end lisp")
