00:00:06,860 --> 00:00:09,270
- Huda Mira and welcome to lesson eight.

2
00:00:09,270 --> 00:00:11,310
In this lesson, you'll
learn how to work with

3
00:00:11,310 --> 00:00:12,950
roles and collections.

4
00:00:12,950 --> 00:00:15,030
I'll start by explaining collections.

5
00:00:15,030 --> 00:00:17,770
A recent addition to the tools
that (indistinct) is offering

6
00:00:17,770 --> 00:00:19,760
to manage your environment.

7
00:00:19,760 --> 00:00:21,590
Next you'll learn how roles make it easy

8
00:00:21,590 --> 00:00:25,100
to integrate standardized
code into your own projects.

9
00:00:25,100 --> 00:00:26,810
You'll learn how Galaxy can be used

10
00:00:26,810 --> 00:00:29,580
to make working with
collections and roles easier.

11
00:00:29,580 --> 00:00:32,040
And after that, you'll
find lessons that explain

12
00:00:32,040 --> 00:00:34,140
how to use roles as well as collections

13
00:00:34,140 --> 00:00:36,660
and how to create your own roles.

14
00:00:36,660 --> 00:00:38,830
At the end of this lesson,
you will find a lab

15
00:00:38,830 --> 00:00:40,830
and lab solution that
allow you to practice

16
00:00:40,830 --> 00:00:42,483
your newly acquired skills.
