Adobe Reader is a program that allows you to look at, print out, and use PDFs.
PDFs are specially formatted documents. They will always look exactly the same on every computer, and are easy to read, easy to print, and easy to use.
All you need to use PDFs is a good PDF reading program. Adobe Reader is the best and most popular PDF reading program. Most computers already have Adobe Reader installed on them. If you do not have Adobe Reader on your computer, or if you have an older, outdated version of Adobe Reader, you may download and install the latest version here. It is safe and easy to do this!
