Poor documentation / cache not working?

[GustavoContreiras-Feegow]

I really liked the lib but I think the documentation is really week in examples...

How to use the cache parameter? Couldn't find any complete example.

The only way I could make cache always refresh is using cache=${new Date().valueOf()} but I know this is not right (I should be using 0 to reset and 1 to keep cache, but that is not working).

Same with join parameter: you find blocks of codes but can't find the classes used in the block of code.
