+"remark-lint" is a code style linter for Markdown files.  See the project's
+page at GitHub for details:
+
+     https://github.com/remarkjs/remark-lint
+
+Note~
+
+Syntastic can't check whether "remark-lint" is installed properly beyond the
+existence of an executable named "remark". Please make sure "remark-lint" is
+installed and working properly before attempting to use it with syntastic.
+
+Checker options~
+
+This checker is initialised using the "makeprgBuild()" function and thus it
+accepts the standard options described at |syntastic-config-makeprg|.
