I need to write Georgian letters in my LaTeX document. Unfortunately I have no idea how computers work, and can just use my TeX because a friend installed it for me. 

It seems I need a package (`\usepackage [language]{babel}`) but I don't think this package is in my computer (if that's the right expression). I have absolutely no idea how to "get" a package or if I have it to make LaTeX "use" it. 

Can anyone tell me how to proceed?

Thanks a lot in advance.

edit: it seems that I have babel, but not it's georgian setting. For example, \usepackage [english]{babel} runs but replacing 'english' with 'georgian' doesn't compile and I gt an error:

exit code 1
/usr/share/texlive/texmf-dist/tex/generic/babel/babel.sty:343: Package babel Error: You haven't specified a language option ...ry to proceed from here, type x to quit}

Also, if relevant, I have pdftex
