-RATIONALE                                                    *fzf-vim-rationale*
-==============================================================================
-
-{fzf}{1} in itself is not a Vim plugin, and the official repository only
-provides the {basic wrapper function}{2} for Vim and it's up to the users to
-write their own Vim commands with it. However, I've learned that many users of
-fzf are not familiar with Vimscript and are looking for the "default"
-implementation of the features they can find in the alternative Vim plugins.
-
-This repository is a bundle of fzf-based commands and mappings extracted from
-my {.vimrc}{3} to address such needs. They are not designed to be flexible or
-configurable, and there's no guarantee of backward-compatibility.

-WHY YOU SHOULD USE FZF ON VIM            *fzf-vim-why-you-should-use-fzf-on-vim*
-==============================================================================
-
-Because you can and you love fzf.
-
-fzf runs asynchronously and can be orders of magnitude faster than similar Vim
-plugins. However, the benefit may not be noticeable if the size of the input
-is small, which is the case for many of the commands provided here.
-Nevertheless I wrote them anyway since it's really easy to implement custom
-selector with fzf.
-
-
-INSTALLATION                                              *fzf-vim-installation*
-==============================================================================
-
-fzf.vim depends on the basic Vim plugin of {the main fzf repository}{1}, which
-means you need to set up both "fzf" and "fzf.vim" on Vim. To learn more about
-fzf/Vim integration, see {README-VIM}{4}.

-
-If you already installed fzf using {Homebrew}{5}, the following should
-suffice:
->
-    Plug '/usr/local/opt/fzf'
-    Plug 'junegunn/fzf.vim'
-<
-But if you want to install fzf as well using vim-plug:
->
-    Plug 'junegunn/fzf', { 'dir': '~/.fzf', 'do': './install --all' }
-    Plug 'junegunn/fzf.vim'
-<
- - `dir` and `do` options are not mandatory
- - Use `./install --bin` instead if you don't need fzf outside of Vim
- - Make sure to use Vim 7.4 or above

-
- - Most commands support CTRL-T / CTRL-X / CTRL-V key bindings to open in a new
-   tab, a new split, or in a new vertical split
- - Bang-versions of the commands (e.g. `Ag!`) will open fzf in fullscreen
- - You can set `g:fzf_command_prefix` to give the same prefix to the commands
-   - e.g. `let g:fzf_command_prefix = 'Fzf'` and you have `FzfFiles`, etc.
-
-(1: `Helptags` will shadow the command of the same name from {pathogen}{10}.
-But its functionality is still available via `call pathogen#helptags()`.)

-
-`fzf#vim#complete` is a helper function for creating custom fuzzy completion
-using fzf. If the first parameter is a command string or a Vim list, it will
-be used as the source.
->
-    " Replace the default dictionary completion with fzf-based fuzzy completion
-    inoremap <expr> <c-x><c-k> fzf#vim#complete('cat /usr/share/dict/words')
-<
-For advanced uses, you can pass an options dictionary to the function. The set
-of options is pretty much identical to that for `fzf#run` only with the
-following exceptions:
-
- - `reducer` (funcref)
-   - Reducer transforms the output lines of fzf into a single string value
- - `prefix` (string or funcref; default: `\k*$`)
-   - Regular expression pattern to extract the completion prefix
-   - Or a function to extract completion prefix
- - Both `source` and `options` can be given as funcrefs that take the completion
-   prefix as the argument and return the final value
- - `sink` or `sink*` are ignored
->
-    " Global line completion (not just open buffers. ripgrep required.)
