2) on the right side in hypershade under "create nodes" press any shader - a lambert will do it.

3) now doubleclick the lambert shader so the attribute editor is opening.

4) in attr editor clock on the checkerbox beside "color" in the first row. choose file from the "Create Render Node" window. attribute editor is active again -> click the folder icon next to the "Image Name"

5) well done -> you set up your shader

6) MMB drag and drop your lambert shader from hypershade onto the object in viewport or activate your geometry in viewport and rightclick lambertShader until context menu opens - choose "Assign Material to Selection"
