53-53: Minor: Clarify the precedence note for better readability.

The current phrasing has awkward grammar and could be clearer. The phrase "for example" with backticks placement and "as per the given URL" are non-standard English constructions.

Consider revising to: "If LOGCHIMP_DB_URL is provided, it will override the individual connection configurations (such as LOGCHIMP_DB_HOST, LOGCHIMP_DB_DATABASE, etc.) and connect using the URL instead."

44-52: Well-structured database configuration documentation.

The new LOGCHIMP_DB_URL variable is clearly documented and appropriately positioned at the top of the database configuration table. The default values are reasonable for a self-hosted deployment guide, and the retention of individual connection variables provides flexibility for users who prefer granular configuration. The critical security reminder on the password field is a nice touch.
