# This is a quick-and-dirty script to install HubCommander.
# This will first download and extract the slackhq/python-rtmbot, and then place
# HubCommander into the proper directory path.

# After the files are fetched, the script will attempt to create the python virtual
# environments and install all the python dependencies (PYTHON 3.5+ IS REQUIRED!)

# You MUST run this from the parent directory that contains this script. So, if this
# script is in a directory named "hubcommander", you must run this from:
# ../hubcommander so that you issue: ./hubcommander/basic_install.sh
