 You can configure the containers [logging driver](https://docs.docker.com/engine/admin/logging/overview/) using the `--log-driver` option if you wish to consume the container logs differently. In the default configuration docker uses the `json-file` driver.
 
+### Slow query logs
+
+By default MySQL doesn't enable [slow query log](https://dev.mysql.com/doc/refman/8.0/en/slow-query-log.html) to record the SQL queries that take a long time to perform. You can modify these settings using the following environment variables:
+
+- `MYSQL_ENABLE_SLOW_QUERY`: Whether to enable slow query logs. Default: `0`
+- `MYSQL_LONG_QUERY_TIME`: How much time, in seconds, defines a slow query. Default: `10.0`
+
 ### Slow filesystems
 
 In some platforms, the filesystem used for persistence could be slow. That could cause the database to take extra time to be ready. If that's the case, you can configure the `MYSQL_INIT_SLEEP_TIME` environment variable to make the initialization script to wait extra time (in seconds) before proceeding with the configuration operations.
