# This script works best when used with the PowerShell Extension in
# VSCode. There is no signed certificate associated with the script
# so you may encounter permissions issues running the script that 
# require you to temporarily change group permissions for executing
# powershell scripts.
#
# Run this script to install all the python libraries and build the
# database file for the Codex-Backend application.
#
# If you do not wish to run the app using Windows, utilize the docker
# commands located in the README_ASU_Branch.md file.

*** NEXT STEPS ***:
1. Setup your '.env' file according to the template in the Repo (.env.template)

2. Make sure you install Docker if you don't already have it installed.

3. Then run the 'starup.ps1' Powershell scripts to start the FastAPI app on windows.

4. Use the 'test.http' commands to make test requests to the API in the docker container.
