To install a font, start at https://www.dafont.com was the site we used. (there are many others)
Steps:
1) download the font and find the folder ( click and show in folder - this should be your student folder at school)
2) on the zip folder, right click and select extract all
3) in the extracted folder select the font files (there may be other text files and image files), right click and select install
4) the fonts will now be available in the Adobe application
The second website we will look at is https://wordmark.it/ This site will show you all the fonts on your computer and will allow you to create a board of selected fonts for you to choose from.
