The documentation for startup is out of date.

[Ren Zuocheng]

Dear all,
I'm new to hadoop and following the documentation for startup users to set up 
my first WordCounter in hadoop. However, I find out that there are some flaws 
in the documentation
An example is the hadoop-core-${HADOOP_VERSION}.jar has been renamed to 
hadoop-common-${HADOOP_VERSION}.jar. There are much more minor errors like 
this, which may cause a novice to feel confused or misled.
And I really want to write an update for that. Can I? If I can, how can I do 
that?
