-To connect to Snowflake, create a **profiles_db.conf** copy of the **profiles_db_template.conf** file, and customize it with your own Snowflake connection parameters, the user name and the account. Your top [default] profile is the active profile, considered by our tool.
-
-Save your password in a SNOWFLAKE_PASSWORD local environment variable. Never add the password or any other sensitive information to your code or to profile files. All names must be case sensitive, with no quotes.

-Without an executable, you can use the source file directly:

 # The Query Result for the Lineage Graph
 
 To repro, you may run the **sql/create-script.sql** file in Snowflake, which is similar to the one described [in the documentation samples](https://docs.snowflake.com/en/user-guide/access-history#example-column-lineage). Wait a few hours, until the changes are propagated in the ACCOUNT_USAGE views.
