 In addition, `nnn` integrates with vidir. vidir supports batch file move and delete.
 
+#### integrate patool
+
+On systems where `atool` is not available but `patool` is, drop two copies of the Python3 script [natool](https://github.com/jarun/nnn/blob/master/scripts/natool) as `atool` and `apack` somewhere in `$PATH`.
+
 #### work faster at rename prompt
 
 The rename prompt supports some bash-like command-line shortcuts - <kbd>^A</kbd>, <kbd>^E</kbd>, <kbd>^U</kbd>. <kbd>^L</kbd> clears the name.

+# natool: a wrapper script to patool to list, extract and create archives
+#
+# usage: natool [-l] [-x] [archive] [file/dir]
+#
+# Examples:
+# - list archive   : natool -l archive.7z
+# - extract archive: natool -x archive.7z
+# - create archive : natool archive.7z archive_dir
+#
+# Brief:
+# natool is written to integrate patool (instead of the default atool) with nnn
+# Two copies of this file should be dropped somewhere in $PATH - atool, apack
