 Above examples are the most likely ones to be needed. However if you configure
 your CMS to host assets on different domain or path, you might need to adjust
 the patterns accordingly.
 
-Keep in mind that you will need to escape special regular expression symbols to avoid creating too permisible patterns:
-
-- `.` should be escaped as `\\.` (dot)
-- `/` should be escaped as `\\/` (slash)
-- your rule should start with `^` so domain matching is exact
-
-If you are using recent versions of Contentful, Drupal or Wordpress source plugins, Gatsby and Netlify Adapter will automatically detect missing Remote Path patterns and will warn you about it and provide require patterns to add to your configuration.
