Step one

The first step it's easy. A simple jump to the Google App Engine an you can find all the informations you need to install

• The python language
• The Google AppEngine

For the next step, Eclipse installation, I decided to use a YouTube video. But that was an error and I spent sometime to found it.

To save time remember

• The right version of eclipse is the Classic One
• At 4:16 of the video the right line to add is "c:\program files\google\google_appengine\dev_appserver.py ." (the fullstop is missing)

The installation was easy but not at the Microsoft level. The price you need to pay for the combination of several environment.
