 <p><strong>pybind11</strong> is a lightweight header-only library that exposes C++ types in Python and vice versa, mainly to create Python bindings of existing C++ code. Its goals and syntax are similar to the excellent <a href="http://www.boost.org/doc/libs/1_58_0/libs/python/doc/">Boost.Python</a> library by David Abrahams: to minimize boilerplate code in traditional extension modules by inferring type information using compile-time introspection.</p>

 ## pybind11 and other unnecessary complications
 
-Sometime, you code is slow and instead of blaming yourself for your poor algorithm, you can blame python. [pybind1](https://github.com/pybind/pybind11) allows you to do just that. 
+Sometime, you code is slow and instead of blaming yourself for your poor algorithm, you can blame python. [pybind11](https://github.com/pybind/pybind11) allows you to do just that. 
 
 > **pybind11** is a lightweight header-only library that exposes C++ types in Python and vice versa, mainly to create Python bindings of existing C++ code. Its goals and syntax are similar to the excellent [Boost.Python](http://www.boost.org/doc/libs/1_58_0/libs/python/doc/) library by David Abrahams: to minimize boilerplate code in traditional extension modules by inferring type information using compile-time introspection.
