Before installing the fonts you have downloaded from Typonine you must unzip (expand) these archive files. The files are zipped (compressed) so you could download them faster. Here are the instructions for unzipping:

Mac

If you are Mac OS X user just double click the .zip archive and the folder, with the same name as the zipped archive, should appear on your desktop. Inside are font files ready for installation.

If you have StuffIt Expander installed on your computer you can use it for extracting files also by double clicking the .zip archive.

Windows

You will need any kind of archiving program such as WINZip, StuffIt, ZipReader, FreeZip, etc. If you already have it installed just double click the .zip archive and the program window should appear. Then click Extract button and the window will appear where you must define the place on your computer where you want to extract the files. Then click extract and the folder, with the same name as the zipped archive, should appear on your defined place.
