 ### Initial Set-up Instructions
-After cloning this repository, you will need a local `.env` file at the root of the directory. Copy the contents or rename the `.env.sample` file to `.env` and update it to include uncommented environment variables for the database credentials `POSTGRES_USER` and `POSTGRES_PASSWORD`, as well as the `DJANGO_SECRET_KEY`. The database credentials can be set to anything while the `DJANGO_SECRET_KEY` will need to be obtained from one of the developers working on the UMIL project. Next you will need to verify the values of the `DEVELOPMENT`, `HOST_NAME`, and `PORT` variables. For local development ONLY, these should be set to "true", "localhost", and "8000" respectively. \
