How to install new font

Install new font in a linux OS is very easy. You need just the true type font that you would install in your computer.
For example if you want install this font downloaded from this website:

You should make a directory in your home, called .fonts (if it doesn't exist):

mkdir ~/.fonts

and then copy or move the file *.ttf, from the place where you have downloaded it (the ~/Downloads dir for example), in the directory just created.

cp ~/Downloads/Satisfaction.ttf ~/.fonts/Satisfaction.ttf

The directory .fonts is hidden as you can see, because the first character is a dot, so you need anable your own file manager to see the hidden folders if you want install the font without command line.
That's all, very easy isn't it?
