     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

 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.
 
+Note: Executing `vim ~/some-directory` will open NERDTree and a new edit window. `exe 'cd '.argv()[0]` sets the `pwd` of the new edit window to `~/some-directory`
