Tutorial for start up file (Rendering with Cycle)

Every time I create a Blender project with Cycle Render Engine  I need perfect settings in all steps. 

Samples

World- Environment settings

HDR-image settings

Lamps-camera.

If I can  do that from one tutorial and then save that one as Start-up file. I dont ner to spend time for that every time I made new project when I have the Basic.
