 ----
 
+NOTE: Liquibase MongoDB is configured using a connection string, we do our best to craft a connection string that matches the MongoDB client configuration but if some configuration properties are not working you may consider adding them directly into the `quarkus.mongodb.connection-string` config property.
+
 Add a changeLog file to the default folder following the Liquibase naming conventions: `{change-log}`
 YAML, JSON and XML formats are supported for the changeLog.
