During this course, I'm going to be performing a lot of demonstrations. I'll be using several different example files throughout the course, and I wanna make sure you can easily follow along with me. The files you see me using in the videos are contained in the course download. Even if you don't want to follow along with me, you'll need the course download in order to complete the practice exercises that you'll do on your own. This download contains the practice exercise instructions as well as the files you'll need to be editing and using, during those practice exercises. With that said, it's very important that you take just a couple of minutes to download the file for this course. You'll find a link to the course download somewhere near this video. Click on it to download that file. Once you've downloaded the file, be sure to extract its contents. If you're using a Mac, you can simply double click the file and it will extract the contents into a folder named vimclass. If you're using windows right, click on the file, then click on extract all. Finally click on the button. If you're using Unix or Linux, use the command unzip -d vimclass vimclass.zip. Whether you're on Mac, windows, Unix, or Linux, you will now have extracted the contents of the course archive into a folder named vimclass. This is where you'll find all the files I use in the lessons and all the files you'll use for the practice exercises, as well as the practice exercise instructions themselves. The practice exercise instructions start with a word exercise and are numbered. So the instructions for the first practice exercise are in the file that starts with the name exercise zero one. There'll be instructions within each exercise telling you exactly what other files you'll need to use, in order to complete the exercise. It's the same way with the lessons. Near the beginning of each video, you'll watch me open a file and start teaching using that file. You'll have a copy of that exact same file, so you can follow along with me if you'd like.
