-Build options
--------------
-
-### With ncurses 6
-
-The official binaries of fzf are built with ncurses 5 because it's widely
-supported by different platforms. However ncurses 5 is old and has a number of
-limitations.
-
-1. Does not support more than 256 color pairs (See [357][357])
-2. Does not support italics
-3. Does not support 24-bit color
-
-[357]: https://github.com/junegunn/fzf/issues/357
-
-But you can manually build fzf with ncurses 6 to overcome some of these
-limitations. ncurses 6 supports up to 32767 color pairs (1), and supports
-italics (2). To build fzf with ncurses 6, you have to install it first. On
-macOS, you can use Homebrew to install it.
-
-```sh
-brew install homebrew/dupes/ncurses
-LDFLAGS="-L/usr/local/opt/ncurses/lib" make install
-```
-
-### With tcell
-
-[tcell][tcell] is a portable alternative to ncurses and we currently use it to
-build Windows binaries. tcell has many benefits but most importantly, it
-supports 24-bit colors. To build fzf with tcell:
-
-```sh
-TAGS=tcell make install
-```
-
-However, note that tcell has its own issues.
-
-- Poor rendering performance compared to ncurses
-- Does not support bracketed-paste mode
-- Does not support italics unlike ncurses 6
-- Some wide characters are not correctly displayed
-

+FZF Vim integration
+===================
+
+This repository only enables basic integration with Vim. If you're looking for
+more, check out [fzf.vim](https://github.com/junegunn/fzf.vim) project.
+
+(Note: To use fzf in GVim, an external terminal emulator is required.)
+
+`:FZF[!]`
+---------
+
+If you have set up fzf for Vim, `:FZF` command will be added.
+
+```vim
+" Look for files under current directory
+:FZF
+
+" Look for files under your home directory
+:FZF ~
+
+" With options
+:FZF --no-sort --reverse --inline-info /tmp
+
+" Bang version starts fzf in fullscreen mode
+:FZF!
+```
+
+Similarly to [ctrlp.vim](https://github.com/kien/ctrlp.vim), use enter key,
+`CTRL-T`, `CTRL-X` or `CTRL-V` to open selected files in the current window,
+in new tabs, in horizontal splits, or in vertical splits respectively.
+
+Note that the environment variables `FZF_DEFAULT_COMMAND` and
+`FZF_DEFAULT_OPTS` also apply here.
+
+### Configuration
+
+- `g:fzf_action`
+    - Customizable extra key bindings for opening selected files in different ways
+- `g:fzf_layout`
+    - Determines the size and position of fzf window (tmux pane or Neovim split)
+- `g:fzf_colors`
+    - Customizes fzf colors to match the current color scheme
+- `g:fzf_history_dir`
+    - Enables history feature
+- `g:fzf_launcher`
+    - (Only in GVim) Terminal emulator to open fzf with
+    - `g:Fzf_launcher` for function reference
+
+#### Examples
+
+```vim
+" This is the default extra key bindings
+let g:fzf_action = {
+  \ 'ctrl-t': 'tab split',
+  \ 'ctrl-x': 'split',
+  \ 'ctrl-v': 'vsplit' }
+
+" Default fzf layout
+" - down / up / left / right
+let g:fzf_layout = { 'down': '~40%' }
+
+" In Neovim, you can set up fzf window using a Vim command
+let g:fzf_layout = { 'window': 'enew' }
+let g:fzf_layout = { 'window': '-tabnew' }
+let g:fzf_layout = { 'window': '10split enew' }
+
+" Customize fzf colors to match your color scheme
+let g:fzf_colors =
+\ { 'fg':      ['fg', 'Normal'],
+  \ 'bg':      ['bg', 'Normal'],
+  \ 'hl':      ['fg', 'Comment'],
+  \ 'fg+':     ['fg', 'CursorLine', 'CursorColumn', 'Normal'],
+  \ 'bg+':     ['bg', 'CursorLine', 'CursorColumn'],
+  \ 'hl+':     ['fg', 'Statement'],
+  \ 'info':    ['fg', 'PreProc'],
+  \ 'prompt':  ['fg', 'Conditional'],
+  \ 'pointer': ['fg', 'Exception'],
+  \ 'marker':  ['fg', 'Keyword'],
+  \ 'spinner': ['fg', 'Label'],
+  \ 'header':  ['fg', 'Comment'] }
+
+" Enable per-command history.
+" CTRL-N and CTRL-P will be automatically bound to next-history and
+" previous-history instead of down and up. If you don't like the change,
+" explicitly bind the keys to down and up in your $FZF_DEFAULT_OPTS.
+let g:fzf_history_dir = '~/.local/share/fzf-history'
+```
+
+`fzf#run`
+---------
+
+For more advanced uses, you can use `fzf#run([options])` function with the
+following options.
+
+| Option name                | Type          | Description                                                      |
+| -------------------------- | ------------- | ---------------------------------------------------------------- |
+| `source`                   | string        | External command to generate input to fzf (e.g. `find .`)        |
+| `source`                   | list          | Vim list as input to fzf                                         |
+| `sink`                     | string        | Vim command to handle the selected item (e.g. `e`, `tabe`)       |
+| `sink`                     | funcref       | Reference to function to process each selected item              |
+| `sink*`                    | funcref       | Similar to `sink`, but takes the list of output lines at once    |
+| `options`                  | string/list   | Options to fzf                                                   |
+| `dir`                      | string        | Working directory                                                |
+| `up`/`down`/`left`/`right` | number/string | Use tmux pane with the given size (e.g. `20`, `50%`)             |
+| `window` (*Neovim only*)   | string        | Command to open fzf window (e.g. `vertical aboveleft 30new`)     |
+| `launcher`                 | string        | External terminal emulator to start fzf with (GVim only)         |
+| `launcher`                 | funcref       | Function for generating `launcher` string (GVim only)            |
+
+`options` entry can be either a string or a list. For simple cases, string
+should suffice, but prefer to use list type if you're concerned about escaping
+issues on different platforms.
+
+```vim
+call fzf#run({'options': '--reverse --prompt "C:\\Program Files\\"'})
+call fzf#run({'options': ['--reverse', '--prompt', 'C:\Program Files\']})
+```
+
+`fzf#wrap`
+----------
+
+`fzf#wrap([name string,] [opts dict,] [fullscreen boolean])` is a helper
+function that decorates the options dictionary so that it understands
+`g:fzf_layout`, `g:fzf_action`, `g:fzf_colors`, and `g:fzf_history_dir` like
+`:FZF`.
+
+```vim
+command! -bang MyStuff
+  \ call fzf#run(fzf#wrap('my-stuff', {'dir': '~/my-stuff'}, <bang>0))
+```
+
+GVim
+----
+
+In GVim, you need an external terminal emulator to start fzf with. `xterm`
+command is used by default, but you can customize it with `g:fzf_launcher`.
+
+```vim
+" This is the default. %s is replaced with fzf command
+let g:fzf_launcher = 'xterm -e bash -ic %s'
+
+" Use urxvt instead
+let g:fzf_launcher = 'urxvt -geometry 120x30 -e sh -c %s'
+```
+
+If you're running MacVim on OSX, I recommend you to use iTerm2 as the
+launcher. Refer to the [this wiki page][macvim-iterm2] to see how to set up.

-Usage as Vim plugin
--------------------
+Vim plugin
+----------
 
-This repository only enables basic integration with Vim. If you're looking for
-more, check out [fzf.vim](https://github.com/junegunn/fzf.vim) project.
-
-(Note: To use fzf in GVim, an external terminal emulator is required.)
-
-#### `:FZF[!]`
-
-If you have set up fzf for Vim, `:FZF` command will be added.
-
-```vim
-" Look for files under current directory
-:FZF
-
-" Look for files under your home directory
-:FZF ~
-
-" With options
-:FZF --no-sort --reverse --inline-info /tmp
-
-" Bang version starts in fullscreen instead of using tmux pane or Neovim split
-:FZF!
-```
-
-Similarly to [ctrlp.vim](https://github.com/kien/ctrlp.vim), use enter key,
-`CTRL-T`, `CTRL-X` or `CTRL-V` to open selected files in the current window,
-in new tabs, in horizontal splits, or in vertical splits respectively.
-
-Note that the environment variables `FZF_DEFAULT_COMMAND` and
-`FZF_DEFAULT_OPTS` also apply here. Refer to [the wiki page][fzf-config] for
-customization.
-
-[fzf-config]: https://github.com/junegunn/fzf/wiki/Configuring-Vim-plugin
-
-#### `fzf#run`
-
-For more advanced uses, you can use `fzf#run([options])` function with the
-following options.
-
-| Option name                | Type          | Description                                                      |
-| -------------------------- | ------------- | ---------------------------------------------------------------- |
-| `source`                   | string        | External command to generate input to fzf (e.g. `find .`)        |
-| `source`                   | list          | Vim list as input to fzf                                         |
-| `sink`                     | string        | Vim command to handle the selected item (e.g. `e`, `tabe`)       |
-| `sink`                     | funcref       | Reference to function to process each selected item              |
-| `sink*`                    | funcref       | Similar to `sink`, but takes the list of output lines at once    |
-| `options`                  | string        | Options to fzf                                                   |
-| `dir`                      | string        | Working directory                                                |
-| `up`/`down`/`left`/`right` | number/string | Use tmux pane with the given size (e.g. `20`, `50%`)             |
-| `window` (*Neovim only*)   | string        | Command to open fzf window (e.g. `vertical aboveleft 30new`)     |
-| `launcher`                 | string        | External terminal emulator to start fzf with (GVim only)         |
-| `launcher`                 | funcref       | Function for generating `launcher` string (GVim only)            |
-
-Examples can be found on [the wiki
-page](https://github.com/junegunn/fzf/wiki/Examples-(vim)).
-
-#### `fzf#wrap`
-
-`fzf#wrap([name string,] [opts dict,] [fullscreen boolean])` is a helper
-function that decorates the options dictionary so that it understands
-`g:fzf_layout`, `g:fzf_action`, `g:fzf_colors`, and `g:fzf_history_dir` like
-`:FZF`.
-
-```vim
-command! -bang MyStuff
-  \ call fzf#run(fzf#wrap('my-stuff', {'dir': '~/my-stuff'}, <bang>0))
-```
+See [README-VIM.md](README-VIM.md).
 
 Tips
 ----
 
-#### Rendering issues
-
-If you have any rendering issues, check the following:
-
-1. Make sure `$TERM` is correctly set. fzf will use 256-color only if it
-   contains `256` (e.g. `xterm-256color`)
-2. If you're on screen or tmux, `$TERM` should be either `screen` or
-   `screen-256color`
-3. Some terminal emulators (e.g. mintty) have problem displaying default
-   background color and make some text unable to read. In that case, try
-   `--black` option. And if it solves your problem, I recommend including it
-   in `FZF_DEFAULT_OPTS` for further convenience.
-4. If you still have problem, try `--no-256` option or even `--no-color`.

-fzf in Go
-=========
-
-<img src="https://cloud.githubusercontent.com/assets/700826/5725028/028ea834-9b93-11e4-9198-43088c3f295d.gif" height="463" alt="fzf in go">
-
-This directory contains the source code for the new fzf implementation in
-[Go][go].
-
-Upgrade from Ruby version
--------------------------
-
-The install script has been updated to download the right binary for your
-system. If you already have installed fzf, simply git-pull the repository and
-rerun the install script.
-
-```sh
-cd ~/.fzf
-git pull
-./install
-```
-
-Otherwise, follow [the instruction][install] as before. You can also install
-fzf using Homebrew if you prefer that way.
-
-Motivations
------------
-
-### No Ruby dependency
-
-There have always been complaints about fzf being a Ruby script. To make
-matters worse, Ruby 2.1 removed ncurses binding from its standard libary.
-Because of the change, users running Ruby 2.1 or above are forced to build C
-extensions of curses gem to meet the requirement of fzf. The new Go version
-will be distributed as an executable binary so it will be much more accessible
-and should be easier to setup.
-
-### Performance
-
-Many people have been surprised to see how fast fzf is even when it was
-written in Ruby. It stays quite responsive even for 100k+ lines, which is
-well above the size of the usual input.
-
-The new Go version, of course, is significantly faster than that. It has all
-the performance optimization techniques used in Ruby implementation and more.
-It also doesn't suffer from [GIL][gil], so the search performance scales
-proportional to the number of CPU cores. On my MacBook Pro (Mid 2012), the new
-version was shown to be an order of magnitude faster on certain cases. It also
-starts much faster though the difference may not be noticeable.
-
-Build
------
-
-See [BUILD.md](../BUILD.md)
-
-Test
-----
-
-Unit tests can be run with `make test`. Integration tests are written in Ruby
-script that should be run on tmux.
-
-```sh
-cd src
-
-# Unit tests
-make test
-
-# Integration tests
-ruby ../test/test_go.rb
-
-# Build binary for the platform
-make
-
-# Install the executable to ../bin directory
-make install
-
-# Make release archives
-make release
-
-# Make release archives for all supported platforms
-make release-all
-```
