+The NERD Tree
+=============
+
+Intro
+-----
+
+The NERD tree allows you to explore your filesystem and to open files and
+directories. It presents the filesystem to you in the form of a tree which you
+manipulate with the keyboard and/or mouse. It also allows you to perform
+simple filesystem operations.
+
+The following features and functionality are provided by the NERD tree:
+
+  * Files and directories are displayed in a hierarchical tree structure
+  * Different highlighting is provided for the following types of nodes:
+    * files
+    * directories
+    * sym-links
+    * windows .lnk files
+    * read-only files
+    * executable files
+  * Many (customisable) mappings are provided to manipulate the tree:
+    * Mappings to open/close/explore directory nodes
+    * Mappings to open files in new/existing windows/tabs
+    * Mappings to change the current root of the tree
+    * Mappings to navigate around the tree
+    * ...
+  * Directories and files can be bookmarked.
+  * Most NERD tree navigation can also be done with the mouse
+  * Filtering of tree content (can be toggled at runtime)
+    * custom file filters to prevent e.g. vim backup files being displayed
+    * optional displaying of hidden files (. files)
+    * files can be "turned off" so that only directories are displayed
+  * The position and size of the NERD tree window can be customised
+  * The order in which the nodes in the tree are listed can be customised.
+  * A model of your filesystem is created/maintained as you explore it. This
+    has several advantages:
+    * All filesystem information is cached and is only re-read on demand
+    * If you revisit a part of the tree that you left earlier in your
+      session, the directory nodes will be opened/closed as you left them
+  * The script remembers the cursor position and window position in the NERD
+    tree so you can toggle it off (or just close the tree window) and then
+    reopen it (with NERDTreeToggle) the NERD tree window will appear exactly
+    as you left it
+  * You can have a separate NERD tree for each tab, share trees across tabs,
+    or a mix of both.
+  * By default the script overrides the default file browser (netw), so if
+    you :edit a directory a (slighly modified) NERD tree will appear in the
+    current window
+  * A programmable menu system is provided (simulates right clicking on a node)
+    * one default menu plugin is provided to perform basic filesytem
+      operations (create/delete/move/copy files/directories)
+  * There's an API for adding your own keymappings
+
+Installation
+------------
+
+[pathogen.vim](https://github.com/tpope/vim-pathogen) is the recommended way to install nerdtree.
+
+    cd ~/.vim/bundle
+    git clone https://github.com/scrooloose/nerdtree.git
+
+Then reload vim, run `:helptags`, and check out `:help NERD_tree.txt`.
+
+
+Faq
+---
+
+Q. Can I have the nerdtree on every tab automatically?
+
+A. Nope. If this is something you want then chances are you aren't using tabs
+   and buffers as they were intended to be used. Read this
+   http://stackoverflow.com/questions/102384/using-vims-tabs-like-buffers
+
+   If you are interested in this behavour then consider [vim-nerdtree-tabs](https://github.com/jistr/vim-nerdtree-tabs)
+
+Changelog
+---------
+
+4.2.0 (2011-12-28)
+
+ * Add NERDTreeDirArrows option to make the UI use pretty arrow chars instead of the old +~| chars to define the tree structure (sickill)
+ * shift the syntax highlighting out into its own syntax file (gnap) * add some mac specific options to the filesystem menu - for macvim only (andersonfreitas)
+ * Add NERDTreeMinimalUI option to remove some non functional parts of the nerdtree ui (camthompson)
+ * tweak the behaviour of :NERDTreeFind - see :help :NERDTreeFind for the new behaviour (benjamingeiger)
+ * if no name is given to :Bookmark, make it default to the name of the target file/dir (minyoung)
+ * use 'file' completion when doing copying, create, and move operations (EvanDotPro)
+ * lots of misc bug fixes (paddyoloughlin, sdewald, camthompson, Vitaly Bogdanov, AndrewRadev, mathias, scottstvnsn, kml, wycats, me RAWR!)
