 #   With ImageMagick installed, this terminal can use the icat kitten to display images.
 #   Refer to kitty documentation for further details.

+#   Users with both tmux and kitty can leverage image previews inside tmux with kitty's icat kitten
+#   - setup kitty as stated above
+#   - tmux >= v3.3a required
+#   - add the following to your tmux.conf:
+#     - `set -g allow-passthrough on`
+#
 #   Wezterm should work out of the box. If `NNN_PREVIEWIMGPROG` is not specified it will use
 #   built in iTerm2 image protocol.
