Here’s a basic guide on how to install fonts on your PC or Mac.
Most downloaded fonts come packed in a zip file ( fontname.zip ) and you’ll need to extract them. In Windows, right click on the zip file and choose Extract All. In Mac OS right click and Open. After that you should end up with a folder containing the font files. If you need to extract rar files you can download and use a free program like 7-zip for Windows or StuffIt Expander for Mac.
