Correct Setup for development help

Hi, sorry me english lvl,

I need info about the correct setup for develop under open Edx (docker) https://github.com/edx/devstack

I’m using Python 2.7
ubuntu 19.04 disco
docker-ce

my question is Python2 or Python3?

Hi Kmogu,
Are you following the official documents to setup your devstack?
I think it would be the most helpful guide. take a look:
