 3 | ## Installation
 4 | 
 5 | * Using [Pathogen](https://github.com/tpope/vim-pathogen), run the following commands:
 6 | 
 7 |         % git clone https://github.com/ferranpm/vim-isolate ~/.vim/bundle/isolate
 8 | 
 9 | ## Usage
10 | 
11 | call `:[range]Isolation` to edit part of a file on a new buffer. When finished,
12 | call `:Isolation` to merge the edited part with the file
13 | Recommended mapping
14 | 
15 |     nnoremap <leader>i vap \| :Isolation<cr>
16 |     vnoremap <leader>i :Isolation<cr>
17 | 
18 | ## Demo
19 | Not Updated to show toggling or explicit ranges (`:n,N Isolation`)
