Download it or install it? To download there should be a link. Click on that and hit save. Now go to the file and unzip if it's a zipped file-right click>extract all. It should take you right to the folder it's in after unzipping. Open that folder and double click on the font file. You'll get a box that pops up and says, "install file?" Click yes. Now shut down the program you are working in then reopen it. The font should appear in your list of fonts.
