Better document SLF4J #19
Description
I've been leaving #13 open for quite a while as I think it raised a real issue: there should be some better documentation about how to get started with Log4s for people who aren't familiar with SLF4J—which is actually pretty simple, but that takes a moment to understand as it's not like other JVM libraries.
However, I don't want to keep #13 open as it can appear that Log4s doesn't support Log4j 2, which is not the case: Log4s works quite well with Logback, Log4j 1, Log4j 2 and java.util.logging.
I'll keep this open to remind myself that I need to write a quickstart guide one day.
