We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
update readme on release of next version
suggest replacing

```**Supports:** python 2.7, 3.5, 3.6```

with:

```[![PyPI pyversions](https://img.shields.io/pypi/pyversions/pandera.svg)](https://pypi.python.org/pypi/pandera/)```

when the new metadata is available on pypi.

It will be 'missing' before pypi is updated:
[![PyPI pyversions](https://img.shields.io/pypi/pyversions/pandera.svg)](https://pypi.python.org/pypi/pandera/)
