+# Logger
+
+The Logger is the [`spdlog`](https://github.com/gabime/spdlog) logging library, with some extras. Like a `Sink` for [`Tracy`](https://github.com/wolfpld/tracy) the Profiler.
+
+# Usage
+
+Each "Section" is ment to have its own "Logger".
+
+To Initialize a section logger with its `sink`s, do `MM::Logger::initSectionLogger("MySection");`.
+Can be placed in the `.enable()` or even the Constructor of your `Service`s.
+
