FYI, this command helped me to solve errors when attempting to install Flit since I had and old pip version, .i.e.

$ python -m pip install --upgrade pip

Hi @tiangolo please take a look when having a chance, thx!

If you have a current version of Python, then pip wouldn't be outdated. What version did you have that Flit conflict with?

Python 3.6.9 which meets FastApi requirements as stated on the main page.

I believe it's important to add the proposed pip upgrade step since I've seen many developers (beginners to seniors) struggling with similar issues in different projects, but it's up to you guys!

Agreed, this should work on Python 3.6.9, and if this makes sure it works for that supported version, I am all for it to include it in the docs! :)

LGTM
