- Throughout the course I'll be using a Mac computer
but it's not a requirement that you do the same.
You can follow along using Windows or Linux as well.
Just make sure you feel comfortable downloading software
and working with the file system.
But don't worry, I'll walk you through every step.
This course comes with exercise files.
You can download them and store it on your Desktop,
like you see here.
The Exercise Files folder is broken into various chapters.
Each chapter corresponds to a chapter of the course.
Inside each directory you will find files
that map to the video.
For example, if you wanted to look for
the third video from chapter four,
you'd come to the chapter four folder and look for 04_03.
If you see files that end in _begin,
this is the state of the file at the beginning of the video,
whereas if you see _end,
this is the state of the file at the end of the video.
But notice, 04_02 and 04_06,
they don't have any _begin or _end.
That's because the code contained in these files
are just for reference.
We're not going to make any changes to those.
This makes it easier for you to compare
the beginning and ending states of our file changes.
Keep in mind though, not all videos
will have exercise files.
But don't worry, I'll make sure to call out
which file we're working with
as we go throughout the course.
