+The files in this directory contain applications or extensions of ranger which
+are put here for your inspiration and as references.
+
+In order to use a plugin from this directory, you need to copy it to
+~/.config/ranger/plugins/
+
+Note that if you update ranger to a new minor version (for example,
+from 1.6.* to 1.7.0), your outdated plugins WILL break and crash ranger.
