Automatically close NERDtree when opening file

I have installed NERDtree 4.1.0.

I have mapped <leader>n to :NERDTreeToggle<CR>.

I would like to use this in a way where I can press <leader>n, then locate the deisred file in the explorer, press enter and have the NERDtree explorer disappear again, automatically.

Can someone help me with this?


Solved by putting let g:NERDTreeQuitOnOpen = 1 in my .vimrc.
