# About SLF4J The Simple Logging Facade for Java (SLF4J) serves as a simple facade or abstraction for various logging frameworks (e.g. java.util.logging, logback, log4j) allowing the end user to plug in the desired logging framework at deployment time. More information can be found on the [SLF4J website](http://www.slf4j.org). # Build Status [](https://travis-ci.org/qos-ch/slf4j) # How to contribute pull requests If you are interested in improving SLF4J, great!

Fork qos-ch/slf4j. Ideally, create a new branch from your fork for your contribution to make it easier to merge your changes back. 3. Make your changes on the branch you hopefuly created in Step 2.
