pip3 command in readme

[jack-rory-staunton]

In the readme, the command:

'pip3 install -f requirements'

should read:

'pip3 install -r ./requirements.text'

At least for me it threw errors.

PS Thanks for this very cool project, I'm looking forward to using it.

Oh sorry yes (and the worst is that I am typing the right command several times per day currently!)
Thank you !

another thing maybe worth adding in the readme is that i also needed to run:

brew install libmagic

on the mac

thank again!
