LE Interface Font change to Civitype FG please? :)

[Talmari]

I'd like to have this font: http://www.dafont.com/civitype-fg.font?a=on&l[]=10&l[]=1

as an interface font. Sadly I can't do it myself (I couldn't find clear instructions at all)

and it would be nice if someone could help me, either by having a tutorial at hand or by doing it yourself.

Would be very grateful!

 

Thank you in advance!
