Easy way to update Fedora

[Deboo ^]

What is the easiest way to update Fedora. I have heard and read a lot
about yum but it has never worked for me, tried it many times on
different machines. I do nto know why, it just hangs on the first
message and nothing happens. What do I need to put in /etc/yum.conf to
make it work? Is there any sample yum.conf that would work out of the
box? And later  could change it to suit me more?

Can someone provide a link to a good yum.conf I could use as a startign point?

Thanks,
Deboo
