yes, of course you can translate it! I’m happy to know that people are interested in FMC and I’d like my work to be accessible to more people. Here is the link to the text in .odt format (I’ve used Libreoffice to write it), in case you need it: http://fmcsolves.cubing.net/fmc_tutorial_ENG.odt
I don’t know about Gitbook, how does it work? Is it similar to github? Anyway, you can put it there if you want, as long as it is clear that I’m the author and you have translated it.
Good luck for your work :)
