 ## Features
+
 - **Configurable log levels**: Set log levels globally or per namespace for detailed control.
 - **Flexible output formats**: Supports JSON, Pretty-print, and custom output adapters.
 - **Context ID support**: Optionally track logs across function calls by assigning a unique context ID.

+By default, `@ekino/logger` outputs `warn` and `error` levels for all namespaces, with logs written to stdout in JSON format.
 
 Adjust the log level globally or per namespace using the `LOG_LEVEL` environment variable or programmatically with `setLevel` and `setNamespaces`.
 
 ### Basic logging
 
-`@ekino/logger` provides five log levels: `trace`, `debug`, `info`, `warn`, and `error`. Setting a specific level enables it and all higher-priority levels.

 ### Force logging

 Override the log level for critical messages by forcing them to be logged:

-logger.debug('Will be logged regardless of level', { forceLogging: true });
+logger.debug('Will be logged regardless of level', { forceLogging: true })
 ```
 
 ## Benchmark
-Below is a performance comparison of several popular Node.js logging libraries, including @ekino/logger. Benchmarks were conducted using Node.js v22.10.0, with results measured in operations per second (higher values indicate better performance).
