Right vs. Wrong mixing coolant?

Is there a right and a wrong way to mix coolant? Like I am about to buy some Mayhem Pastel and the mix ratio is 250mL concentrate to 750mL DI water do I just pour into a jug and shake? Or stir idk.... I am just trying to get everything figured out before I jump headfirst. 

You're best to just stir it together. Shaking it will trap small air bubbles in the fluid which will increase the time for the system to bleed.

Awesome Thank you :D
