All Techy fonts are original True Type Fonts (.ttf), which work on both Mac and Windows.
You may use these fonts for personal use. No attribution needed, but one is appreciated.
To install these fonts on most systems it's as easy as opening the font and clicking "install." If that doesn't work, try searching the web for your specific operating system and ".ttf fonts" to find directions!
You will receive a zipped file with the font inside. Just open the file to unzip it.
