 cpp-peglib
 ==========
 
+[![Build Status](https://travis-ci.org/yhirose/cpp-peglib.svg?branch=master)](https://travis-ci.org/yhirose/cpp-peglib)
+
 C++11 header-only [PEG](http://en.wikipedia.org/wiki/Parsing_expression_grammar) (Parsing Expression Grammars) library.
 
 *cpp-peglib* tries to provide more expressive parsing experience in a simple way. This library depends on only one header file. So, you can start using it right away just by including `peglib.h` in your project.
