1. `pip` won't install requests automatically. This should be put inside `setup.py`. (without `requests` whole package doesn't run at all so it's really bad experience for users -- they might simply think the whole thing is broken and try to find an alternative)
2. Please use `>=`. This is a tool, thus should not bind to any particular version. Otherwise, user that already use other version of `requests` inside their project wouldn't be able to use this package.
