Basic commands for MySensors?

[Plakevi]

I have tried to google basic commands for sending/receiving info to Vera, but i am now more confuced than before. I have been reading examples but i am newbie both in Arduino and MySensors so almost every example seems to be too complex. For example i tried to combine "relay actuator" and "relay actuator with push button" to create multiple relays and push buttons in one sketch, but i cant get it working properly. I know how for loop works, but that is one of many things that is confusing me at the end
So is there any place to get basic commands from node to gateway in one place, so I can do some sketches and learn with try and error principle?

MYSController is good when debugging.

There are numerous examples to get inspired from on the main site (or /examples if you've downloaded the library).
