 This project gives an example of ONAP-compliant logging using SLF4J logging.
 
-## Adapter
-
-In ```org.onap.logging.ref.slf4j.common```, there are TWO classes:
-1. ```org.onap.logging.ref.slf4j.common.ONAPLogConstants```, providing declarations of standard ONAP Markers, MDCs and HTTP headers.
-2. ```org.onap.logging.ref.slf4j.common.ONAPLogAdapter```, providing a lightweight, compliant implementation of the ONAP logging spec.
-
-The adapter provides:
-1. A loosely-coupled SLF4j logging wrapper:
- * To be used for logging ONAP ```entry```, ```exit``` and ```invoke``` behavior.
- * Devolving all *application* logging to the component, via the regular SLF4J ```Logger``` facade.
-2. Customization options:
- * *Cheap*, by way of bean properties. This is suited to most Use Cases.
- * *Sophisticated*:
-    * By OPTIONALLY implementing one of a number of adapters:
-      * ```RequestAdapter``` to read incoming headers.
-      * ```ServiceDescriptor``` for reporting attributes of the current service.
-      * ```ResponseDescriptor``` for reporting outcomes.
-      * ```RequestBuilder``` for setting southbound request headers.
-    * By OPTIONALLY overriding methods like ```ONAPLogAdapter#setMDCs(RequestAdapter)```.
-
-Note that:
-* The adapter implementation uses static inner classes in order to fit in a single source file. This was an objective.
