[NTG-context] French interface - previous message = wrong title

Hi, I try to update and to fill the french content of mult-def.lua. Currently, I have an updated "mult-def.lua" file. 3 questions : 1/ which commands should be executed in order to make the new local interface effective with context 2/ which commands should be executed in order to build a local version of setup-fr.pdf 3/ many commands in setup-fr.pdf are not documented in mult-def.lua where does the additionnal translations should come from ? Thanks a lot for your precious help.
