Installing fonts <3
Go to Dafont.com, choose the font of your choice! & click download! Sidenote: please be sure that the font you choose says "100% free" if you plan to use it in a graphic you are going to sell! some fonts are only ok for PERSONAL use, for products you are not selling, but if you want to BUY a license to use the font, then thats different. OK, now once you've got your font downloaded, a downloads tab should pop up, showing the file, click on it, (heres what mine looks like, just to give you an idea)
Next, you'll have this pop up, Click on your files like the ones i have circled below-

Now its pretty self explanatory here, look for "Install" at the top! & click it.

Your font should now be in photoshop, go to your text tool in photoshop, & then search it by name at the top!
