Nomination: documentation tool to consider while user manual is migrated

hi all,

the Blender user manual presently makes use of sphinx documentation tool.
i understand its implementation is clean and simple.

just like the migration of blender code from SVN to Git, there shall come a time when these user manual texts need to be migrated too.
if there is an existing plan drafted for migrating these docs using Git tools then it is fine.

on the other hand i would like to nominate the documentation tool used by MathWorks → Documentation - MATLAB & Simulink - MathWorks India
i am yet to research on what they are using but somehow i felt their UI/UX is very clean. this however is a personal opinion.

i do not mean to step on others toes while making this nomination, please treat this as a request.
