So tomorrow my new Ti Nspire Cx Cas calc arrives.

Its my first texas instruments / graph calc, and i know theres a "scene" with mods and "apps" to make cool shit like step by step derivation, integration, complex step by step equations and shit like that, anybody knows a good place to start learning how to use it.

I really need a place to start I know there are over featured apps for this model, but the cost of three is almost the price of the calc, so I need a specialized site to look up cracked apps, or whatever calc-terminology they use. I've tried the pirate bay, Google, obviously, but it appears there aren't many mainstream forums or sites, so I guess someone here should have a tip

tl;dr:
>I have a new graph ti calc, never had one before
>i need to know how to used to take the most of it, to mod it,
>install cracked apps (whats a good site, with tutorials)
>Mainly for making my live easier in my tests
>Help please
