+##### A python wrapper for *junegunn*'s awesome [fzf](https://github.com/junegunn/fzf).
+
+![](https://raw.githubusercontent.com/nk412/pyfzf/master/pyfzf.gif)
+
+Requirements
+------------
+
+* Python 3.6+
+* [fzf](https://github.com/junegunn/fzf)
+
+*Note*: fzf must be installed and available on PATH.
+
+Installation
+------------
+	pip install pyfzf
+
+Usage
+-----
+    >>> from pyfzf.pyfzf import FzfPrompt
+    >>> fzf = FzfPrompt()
+
+If `fzf` is not available on PATH, you can specify a location
+
+    >>> fzf = FzfPrompt('/path/to/fzf')
+
+Simply pass a list of options to the prompt function to invoke fzf.
+
+    >>> fzf.prompt(range(0,10))
+
+You can pass additional arguments to fzf as a second argument
+
+    >>> fzf.prompt(range(0,10), '--multi --cycle')
+
+Input items are written to a temporary file which is then passed to fzf.
+The items are delimited with `\n` by default, you can also change the delimiter
+(useful for multiline items)
+
+    >>> fzf.prompt(range(0,10), '--read0', '\0')
