To configure your BigQuery environment, please follow the steps below:
Go to https://console.cloud.google.com (If you don't have a GCP account, please create it - it's free of charge).
Create a new project.
Switch to the "Editor" tab. This is where you can write your SQL queries. The tables that you query can then be saved for manipulating data using other tools.
You're ready to go! Best of luck!
