getting start

get started...

which is right? and why is it right?

Of course, I know getting started is right. but want to know well in grammar

"Get started" is a so called "get passive" in the form, but it is used as an intransitive verb. It is very frequently used in speech in the meaning of "start work" or "start to be active". (EX) Come on, boys, let's get started!

"Getting started" is a present participle or gerund of "get started". As seen in the page linked by W3, "getting started (with X)" is a phrase routinely used at the beginning of an instruction manual for using any tool (=X).

Well, to get started...

Getting started and get started are ok depending on context. We don't use getting start.

Getting started is difficult to use, it means you are in the process of some initial event, activity, etc..
