1
00:00:02,860 --> 00:00:05,150
This course contains a lot of new information.

2
00:00:05,170 --> 00:00:08,250
So to make that information a little easier to digest.

3
00:00:08,350 --> 00:00:13,050
I've included a PD f reference guide with the third edition of this course.

4
00:00:13,060 --> 00:00:19,060
This is essentially a one hundred and twelve page e-book which contains lecture notes code examples

5
00:00:19,270 --> 00:00:23,950
and documentation links for each and every lesson in the class.

6
00:00:23,950 --> 00:00:29,930
So video is my favorite medium for learning something new but it ends up being a poor reference tool.

7
00:00:30,010 --> 00:00:35,530
If you forget what something was called or how it works it can be really time consuming to dig through

8
00:00:35,530 --> 00:00:40,250
hours of video to find that one little piece of information you're looking for.

9
00:00:40,270 --> 00:00:45,810
The goal with the PD f reference guide is to give you this information in a way that's easily scandal

10
00:00:46,060 --> 00:00:49,220
so you can find exactly what you were looking for.

11
00:00:49,240 --> 00:00:56,110
You can download the F reference guide as part of the lecture downloads for this lesson so take a moment

12
00:00:56,140 --> 00:00:57,450
to download it now.

13
00:00:57,460 --> 00:00:59,040
So you have it when you need it.

14
00:00:59,410 --> 00:01:01,780
All right that's it for this welcome section.

15
00:01:01,780 --> 00:01:03,700
Let's jump in to the rest of the class.
