+## Configuring project requirements and pre-commit
+Having pre-commit configured in your local environment is crucial to lessen the linting mistakes passed in the commits as the pre-commit does the sqlfluff lint and fix for the changes to be added in the commit. In order to configure it, do:

 ### Oauth
 5. Oauth - Follow the GCP CLI installation guide [here](https://cloud.google.com/sdk/docs/install). After the installation, run `gcloud init` and provide the requested account information in order to properly setup your Oauth GCP account. The account will be used to run the queries and access the database, so you should use your GCP personal account for that.
