+SUMMARY="The missing terminal file manager for X"
+DESCRIPTION="
+nnn is a full-featured terminal file manager. It's tiny and nearly 0-config with an incredible performance.
+
+nnn is also a du analyzer, an app launcher, a batch renamer and a file picker. The plugin repository has tons of plugins and documentation to extend the capabilities further. You can plug new functionality and play with a custom keybind instantly. There's an independent (neo)vim plugin.
+
+It runs smoothly on the Raspberry Pi, Termux on Android, Linux, macOS, BSD, Cygwin, WSL and works seamlessly with DEs and GUI utilities.
+
+Visit the Wiki for concepts, program usage, how-tos and troubleshooting.
