Porting of 2-steps docs

[dbrattli]

Need to figure out what to do with the template setup. What should we use as an alternative?

[jkone27]

i suggest for python maybe there should be a way also to start as scripting only,

• one template (minimal) for scripting only : all deps in 1 file .fsx script with #r s
• one template (standard) for bigger projects, using the approaches described already in examples
