The new installer is one of the most important featres of the new Limesurvey 2.0 version. Once the English instructions page (see this idea) was set up, the French translation of that page has to be created.
Task Steps:

• Have a look at the english installer page once it was set up.
• Create the French translation of this page directly at our wiki.
• Check if your new/updated translation contains all information of the english base version.
• Discuss the translation with your mentor
