+# Log4j 1.2 Bridge
+
+The Log4j 1.2 Bridge allows applications coded to use Log4j 1.2 API to use Log4j 2 instead.
+
+## Requirements
+
+The Log4j 1.2 bridge is dependent on the Log4j 2 API. The following Log4j 1.x methods will behave differently when
+the Log4j 2 Core module is included then when it is not:
+
+| Method | Without log4j-core | With log4j-core |
+| ----------------------------- | ------------------ | ------------------------------------ |
+| Category.getParent() | Returns null | Returns parent logger |
+| Category.setLevel() | NoOp | Sets Logger Level |
+| Category.setPriority() | NoOp | Sets Logger Level |
+| Category.getAdditivity() | Returns false | Returns Logger's additivity setting |
+| Category.setAdditivity() | NoOp | Sets additivity of LoggerConfig |
+| Category.getResourceBundle() | NoOp | Returns the resource bundle associated with the Logger |
+| BasicConfigurator.configure() | NoOp | Reconfigures Log4j 2 |
+
+If log4j-core is not present location information will not be accurate in calls using the Log4j 1.2 API. The config
+package which attempts tp convert Log4j 1.x configurations to Log4j 2 is not supported without Log4j 2.
+
+For more information, see [Runtime Dependencies](../runtime-dependencies.html).
+
+## Usage
+
+To use the Log4j Legacy Bridge just remove all the Log4j 1.x jars from the application and replace them
+with the bridge jar. Once in place all logging that uses Log4j 1.x will be routed to Log4j 2. However,
+applications that attempt to modify legacy Log4j by adding Appenders, Filters, etc may experience problems
+if they try to verify the success of these actions as these methods are largely no-ops.
