+Building fzf
+============
+
+Build instructions
+------------------
+
+### Prerequisites
+
+- `go` executable in $PATH
+
+### Using Makefile
+
+Makefile will set up and use its own `$GOPATH` under the project root.
+
+```sh
+# Source files are located in src directory
+cd src
+
+# Build fzf binary for your platform in src/fzf
+make
+
+# Build fzf binary and copy it to bin directory
+make install
+
+# Build 32-bit and 64-bit executables and tarballs
+make release
+
+# Build executables and tarballs for Linux using Docker
+make linux
+```
+
+### Using `go get`
+
+Alternatively, you can build fzf directly with `go get` command without
+cloning the repository.
+
+```sh
+go get -u github.com/junegunn/fzf/src/fzf
+```
+
+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
+
