-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
-```
