# The NERDTree 
## Introduction
The NERDTree is a file system explorer for the Vim editor. Using this plugin, users can visually browse complex directory hierarchies, quickly open files for reading or editing, and perform basic file system operations.
## Installation
Use your favorite plugin manager to install this plugin. tpope/vim-pathogen, VundleVim/Vundle.vim, junegunn/vim-plug, and Shougo/dein.vim are some of the more popular ones. A lengthy discussion of these and other managers can be found on vi.stackexchange.com. Basic instructions are provided below, but please **be sure to read, understand, and follow all the safety rules that come with your ~~power tools~~ plugin manager.**
If you have no favorite, or want to manage your plugins without 3rd-party dependencies, consider using Vim 8+ packages, as described in Greg Hurrell's excellent Youtube video: Vim screencast #75: Plugin managers.

## Getting Started
After installing NERDTree, the best way to learn it is to turn on the Quick Help. Open NERDTree with the `:NERDTree` command, and press `?` to turn on the Quick Help, which will show you all the mappings and commands available in the NERDTree.

## NERDTree Plugins
NERDTree can be extended with custom mappings and functions using its built-in API. The details of this API are described in the included documentation. Several plugins have been written, and are available on Github for installation like any other plugin.
