Instapaper-cli requires requests.
Don't have requests? just run
pip install requests or
pip install -r requirements.txt to install it.
Copy the config file;
cp config.py.sample config.py
Edit config.py, set up your Instapaper account
instapaper_user = 'user'
instapaper_pass = 'pass'
It's quite simple...
