 Hi there  @KaushikBukka 

If you are using sharepoint you can also do the following

• On the Create K2 Application page, select the check box next to the Workflow element


• A section will appear where you need to provide some settings for the workflow

Specify how the workflow gets started

• Under "when the following events occur" check the box for "An item was added"

I think this should help you with the workflow instances. You can have a look at the link below for reference
