+ <small>colorscheme <a href="https://github.com/nightsense/snow">snow</a></small>
+</p>
+
+### Requirements
+
+1. nnn (minimum version 2.2)
+2. Neovim or Vim 8.1 with terminal support
+
+### Install
+
+You must install nnn itself. Instructions
+[here](https://github.com/jarun/nnn#installation).
+
+Then install using your favorite plugin manager:
+
+```vim
+" using vim-plug
+Plug 'mcchrish/nnn.vim'
+```
+
+### Usage
+
+To open nnn as a file picker in vim/neovim, use the command `:NnnPicker` or
+`:Np` or the key-binding `<leader>n`. You can pass a directory to `:NnnPicker`
+command and opens nnn from there e.g. `:NnnPicker path/to/somewhere`.
+
+Once you [select](https://github.com/jarun/nnn#selection) one or more files and
+press <kbd>enter</kbd>, vim quits the nnn window and opens the first selected
+file and add the remaining files to the arg list/buffer list.
+
+Pressing <kbd>enter</kbd> on a file in nnn will pick any earlier selection, pick
+the file and exit nnn.
+
+To discard selection and exit, press <kbd>^G</kbd>.
+
+Please visit the complete documentation by running `:help nnn`.
+
+### Configurations
+
+#### Custom mappings
+
+```vim
+" Disable default mappings
+let g:nnn#set_default_mappings = 0
+
+" Then set your own
+nnoremap <silent> <leader>nn :NnnPicker<CR>
+
+
+" Or override
+" Start nnn in the current file's directory
+nnoremap <leader>n :NnnPicker '%:p:h'<CR>
+```
+
+#### Layout
+
+```vim
+" Opens the nnn window in a split
+let g:nnn#layout = 'new' " or vnew, tabnew etc.
+
+" Or pass a dictionary with window size
+let g:nnn#layout = { 'left': '~20%' } " or right, up, down
+```
+
+#### Action
+
+You can set extra key-bindings for opening files in different ways. Nothing is
+set by default to not override nnn's own key-bindings.
+
+```vim
+let g:nnn#action = {
+ \ '<c-t>': 'tab split',
+ \ '<c-x>': 'split',
+ \ '<c-v>': 'vsplit' }
+```
+
+For example, when inside an nnn window, pressing <kbd>ctrl-t</kbd> will open the
+selected file in a tab, instead of the current window. <kbd>ctrl-x</kbd> will
+open in a split an so on. Meanwhile for multi selected files will be loaded in
+the buffer list.
+
+#### Command override
+
+When you want to override the default nnn command and add some extra flags.
+Example you want to start nnn in light mode.
+
+```vim
+let g:nnn#command = 'nnn -l'
+
+" or pass some env variables
+let g:nnn#command = 'NNN_RESTRICT_NAV_OPEN=1 nnn -l'
+```
+
+#### `nnn#pick()`
+
+The `nnn#pick([<dir>][,<opts>])` function can be called with custom directory
+and additional options such as opening file in splits or tabs. Basically a more
+configurable version of `:NnnPicker` command.
+
+```vim
+call nnn#pick('~/some-files', { 'edit': 'vertical split' })
+" Then you can do all kinds of mappings if you want
+```
+
+`opts` can be:
+
+- `edit` - type of window the select file will be open.
+- `layout` - same as `g:nnn#layout` and overrides it if specified.
+
+#### Environment variables
+
+You can define env variables in `vimrc` and nnn will detect it.
+
+```vim
+let $NNN_RESTRICT_NAV_OPEN=1
+```
