+= JBoss Logging
+
+JBoss Logging is a logging facade which can bind to different log managers allowing your applications to be log manager
+agnostic.
+
+== Usage
+
+JBoss Logging is similar to other logging facades in the way you get a logger and log messages. One thing to note is
+the format style log methods will only format the message if the log level is enabled. This helps with performance of
+objects which may have complex `toString()` methods.
+
+[source,java]
+----
+private static final Logger LOGGER = Logger.getLogger(Customer.class);
+
+public Customer getCustomer(final int id) {
+    LOGGER.debugf("Looking up customer %d", id);
+    try {
+        final Customer customer = findCustomer(id);
+        LOGGER.tracef("Found customer: %s", customer);
+        return customer;
+    } catch (Exception e) {
+        LOGGER.errorf(e, "Error looking up customer %d", id);
+    }
+    return null;
+}

+
+=== Supported Log Managers
+
+The following are the supported log managers and listed in the order the attempt to discover the provider is done.
+
+1. JBoss Log Manager
+2. https://logging.apache.org/log4j/2.x/[Log4j 2]
+3. https://logback.qos.ch/[SLF4J and Logback]
+4. https://logging.apache.org/log4j/1.2/[log4j] (note this log manager is EOL'd)
+5. Java Util Logging
+
+You can define the specific log manager you want to use by specifying the `org.jboss.logging.provider` system property.
+The following is the mapping of the property value to the log manager.
+
+|===
+|Property Value |Log Manager
+
+|jboss
+|JBoss Log Manager
+
+|jdk
+|Java Util Logging
+
+|log4j2
+|Log4j 2
+
+|log4j
+|log4j
+
+|slf4j
+|SLF4J and Logback
+|===
+
+=== Custom Provider
+
+You can also implement your own `org.jboss.logging.LoggerProvider` which would be loaded from a `ServiceLoader`. Simply
+implement the API and add a `META-INF/services/org.jboss.logging.LoggerProvider` file with the fully qualified class
+name of your implementation to your library. If the system property is not defined, your implementation should be
+discovered.
+
