New dashboard feature walkthrough

I am currently designing a new dashboard feature for a data-driven recruitment managers. Feature should allow them to manage costs of their current positions and edit/delete/view them for a more precise result of campaigns. It is a first interactive feature of the whole dashboard and I was thinking to implement a "walkthrough" like this.

or a "do-something" approach to engage the users and show them how to work with the feature by do-and-learn method forcing them to click on the most basic functions and let him go from there.

My question is which of these two is better and follow-up question are there guidelines/patterns to implement these that you know of?
