####[pathogen.vim](https://github.com/tpope/vim-pathogen)
cd ~/.vim/bundle
git clone https://github.com/scrooloose/nerdtree.git
git clone https://github.com/scrooloose/nerdtree.git ~/.vim/bundle/nerdtree

__Q. Can I have the nerdtree on every tab automatically?__
> Is there any support for `git` flags?
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
Yes, install [nerdtree-git-plugin](https://github.com/Xuyuanp/nerdtree-git-plugin).
If you are interested in this behaviour then consider [vim-nerdtree-tabs](https://github.com/jistr/vim-nerdtree-tabs)

Stick this in your vimrc:
autocmd StdinReadPre * let s:std_in=1
autocmd VimEnter * if argc() == 0 && !exists("s:std_in") | NERDTree | endif
__Q. How can I map a specific key or shortcut to open NERDTree?__
Note: Now start vim with plain `vim`, not `vim .`
A. Stick this in your vimrc to open NERDTree with `Ctrl+n` (you can set whatever key you want):

> How can I open NERDTree automatically when vim starts up on opening a directory?
`map <C-n> :NERDTreeToggle<CR>`
autocmd StdinReadPre * let s:std_in=1
autocmd VimEnter * if argc() == 1 && isdirectory(argv()[0]) && !exists("s:std_in") | exe 'NERDTree' argv()[0] | wincmd p | ene | endif
__Q. How can I close vim if the only window left open is a NERDTree?__
This window is tab-specific, meaning it's used by all windows in the tab. This trick also prevents NERDTree from hiding when first selecting a file.
A. Stick this in your vimrc:

> How can I map a specific key or shortcut to open NERDTree?

map <C-n> :NERDTreeToggle<CR>

> How can I close vim if the only window left open is a NERDTree?
4.2.0 (2011-12-28)
Stick this in your vimrc:
* 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!)
autocmd bufenter * if (winnr("$") == 1 && exists("b:NERDTree") && b:NERDTree.isTabTree()) | q | endif

> How can I change default arrows?
Use these variables in your vimrc. Note that below are default arrow symbols

let g:NERDTreeDirArrowCollapsible = '▾'
