Update readme on how to connect to MongoDB free cluster #30
Description
We will use mongodb cloud to store data. Please create a section in the readme on what env variables need to be set for a MongoDB connection
Definition of Done:
- Using the dotenv library, use env variables to get connection to mongodb.
- create a .env file that declares the names of env variables but does not set them equal to anything
- use .env.local to keep a personal connection to mongodb
- Section in readme created about mongoDB
