How to start developing custom VirtueMart 3 plugin

[ns1]

Hi

I would like to develop a custom virtuemart plugin and am looking for some documentation or tutorial but can't find any for VM3. Only some for VM2.
Can anyone point me in the right direction?

Thank you...

search the install for triggers that u can use
