Setup MongoDB

In this example I use mongodb.com

Create an account and create a Cluster (you can use a free plan)

Select Compass option to connect.

If you not have Compass installed, install it from https://www.mongodb.com/try/download/compass

Copy the connection URI.

Go to "Network Access" in "SECURITY" section and add the IP ADDRESS "0.0.0.0/0"

In your Compass aplication, paste the connection URI, and pess Connect.

Finally create a new database with the collection "guilds".
