How to translate documentation/online help?

Hello everyone,
How to translate the online help in:

https://help.libreoffice.org/latest/ar/text/shared/05/new_help.html

A translator wishes to work only on documentation translation into Arabic
and I failed to figure it out from the instructions on the wiki!

Thank you in advance!
