Juju charm hook vs. state

[fengxia]

I'm learning charm development and confused about state vs. hook.

I used @when_not("state.0") to mark the very first function that gets 
executed. In document it also says "install" hook will be the first to 
execute. Tried @hooks.hook("install") but it just failed at charm 
installation.

So what is the right way to determine the "entry" point in a charm? I 
mean the first function block that will be executed. I'm thinking to use 
chained state from that point on to guide execution process. Is this the 
right approach?
