+
+## Overview
+
+Spring Boot starter for nrich-logging module. The purpose of nrich-logging is to provide a unified and configurable logging format. It is used by nrich-webmvc module to log exceptions, it also allows
+logging level and logging verbosity (details about exception) to be easily configured through `message.properties`.
+Starter module provides a `@Configuration` class with default configuration of nrich-logging module (while allowing for overriding with conditional annotations) and does automatic registration
+through `spring.factories`.
+
+## Usage
+
+### Adding the Dependency
+
+The artifact is published on [Maven Central Repository][Maven Central]. To include the dependency use the following configurations.
+
+With Maven:
+
+```xml
+
+<dependency>
+    <groupId>net.croz.nrich</groupId>
+    <artifactId>nrich-logging-spring-boot-starter</artifactId>
+    <version>${nrich.version}</version>
+</dependency>
+
+```
+
+With Gradle:
+
+```groovy
+implementation "net.croz.nrich:nrich-logging-spring-boot-starter:${nrich.version}"
+```
+
+Note if using nrich-bom dependency versions should be omitted.
+
+### Using the library
+
+After adding the dependency a bean of type `LoggingService` is available for dependency injection. The purpose of the `LoggingService` it to be used by `NotificationErrorHandlingRestControllerAdvice`
+to log uncaught exception but users can also use it to manually log caught exceptions. An example usage is given bellow (more detailed examples are found in nrich-logging README.MD):
+
+```java
+
+@RequiredArgsConstructor
+@Service
+public class ExampleService {
+
+    private final LoggingService loggingService;
+
+    public void executeAction() {
+        try {
+            // some operation that can throw an exception
+        }
+        catch (Exception exception) {
+            loggingService.logInternalException(exception, null);
+        }
+    }
+}
+
+
+```
