+`nnn` is also a disk usage analyzer, a fuzzy app launcher, a batch file renamer and a file picker. The [plugin repository](https://github.com/jarun/nnn/tree/master/plugins#nnn-plugins) has tons of plugins and plugin-specific documentation to extend the capabilities further. There's an independent [(neo)vim plugin](https://github.com/mcchrish/nnn.vim).
 
 It runs smoothly on the Raspberry Pi, Termux [on Android](https://www.youtube.com/watch?v=AbaauM7gUJw), Linux, macOS, BSD, Cygwin and Linux subsystem for Windows. `nnn` works seamlessly with DEs and GUI utilities. It's nearly zero-config (with sensible defaults) and can be setup in less than 5 minutes.

+## Introduction
+
 Plugins extend the capabilities of `nnn`. They are _executable_ scripts (or binaries) which `nnn` can communicate with and trigger. This mechanism fits perfectly with the fundamental design to keep the core file manager lean and fast, by delegating repetitive (but not necessarily file manager-specific) tasks to the plugins.
