So at first install latest PSoC Creator. Unfortunately, AFAIK, PSoC Creator for 6th gen boards is not yet available - but in the meanwhile, just install what is available, and you can start.
The boards are unavailable at this time, too, but if you are new to this, I would recommend you to get started with single-core MCUs, like PSoC 5.
Then, inside PSoC Creator there are datasheets for components. Do a search on this web, there are surely a few examples (or maybe builtin in PSoC Creator - I am not sure).
Also, I hope that you understand, that the board itself without external circuitry(or onboard peripherals, if there are any) is almost useless, so you will need to learn this too - again do a search on the internet, there is certainly something available.
Feel free to ask, if you have any other questions, or you do not understand something.
