When writing code with a new framework it usually pays to go
through the basic tutorials sufficiently that you understand
how it works. If you don't know what the various parameters
are for then you are almost certainly going to spend a lot
of your life hunting for solutions. My old teacher used to
call it "poke and hope", it's a very slow and inefficient
way to work.

Spending a day (or two) working through a detailed tutorial
that explains how the framework does things will save a
lot of time hunting for some random code that works
(possibly by accident!) Don't just type (or paste) in
the examples, pay attention to the explanations. If the
tutorial doesn't explain its not a good tutorial,
find another. Learning by example is only good for
getting started. You need understanding too.
