Minor issues in the documentation

[expectopatronum]

Hi again,
while reviewing I noticed a few minor things in the README/documentation:

• I don't see a statement of need in the documentation. There is a detailed statement of need in the paper but the review check list also asks for a statement of need in the documentation.
• The info can be found from setup.py but for me as a user it would be helpful to see at one glance which Python version is required (e.g. in the README in section "Installing")
• Community Guidelines: There is a section regarding contributing, but it does not mention how to "Report issues or problems with the software" or "Seek support", although I would expect it through the same channels (mail to the main author, github issue).

Best regards
Verena

Many thanks for these points. I addressed them in the commit 1ad2124.

Best,
