All of the above resources are great! I benefited a lot from the new to qlik sense vidoes and also worked through the tutorial that comes with the Qlik sense desktop. The location of the PDF/Tutorial depends on how you installed the app but here's an example: C:\Users\<<username>>\Documents\Qlik\Sense\Tutorials\Qlik Sense developer\Instructions Hope that helps!
