1
00:00:00,000 --> 00:00:03,947
Welcome. If you have never written code,
start here.

2
00:00:03,947 --> 00:00:07,779
Code is a set of instructions that tells a
computer what to do.

3
00:00:07,779 --> 00:00:10,774
A website keeps those instructions in files.

4
00:00:10,774 --> 00:00:13,897
You do not have to write them yourself to
begin this lesson.

5
00:00:13,897 --> 00:00:17,206
Claude Code can help read and change a
project.

6
00:00:17,206 --> 00:00:21,141
You describe the result you want, and you
check the result it produces.

7
00:00:21,141 --> 00:00:25,646
In an ordinary chat, you might ask for advice
and receive an explanation.

8
00:00:25,646 --> 00:00:29,988
Here, you will eventually let Claude work on
files in a folder you choose.

9
00:00:29,988 --> 00:00:32,182
This orientation is a rehearsal.

10
00:00:32,182 --> 00:00:36,362
The practice screens are illustrations, not a
live Claude session.

11
00:00:36,362 --> 00:00:39,682
Nothing here installs software or changes
your computer.

12
00:00:39,682 --> 00:00:43,954
Our small goal is to change a reading list
heading and see that change on the

13
00:00:43,954 --> 00:00:46,659
page. No jargon to memorize.

14
00:00:46,659 --> 00:00:52,348
No race to finish. After this orientation,
the next lesson walks through installation

15
00:00:52,348 --> 00:00:57,886
and a fuller project. Using Claude Code for
real requires supported account

16
00:00:57,886 --> 00:01:01,624
access; this free lesson does not include
that access.

17
00:01:01,633 --> 00:01:04,617
Let us name the windows before we move
between them.

18
00:01:04,617 --> 00:01:10,190
Your browser is the app showing this lesson,
such as Chrome, Edge, or Safari.

19
00:01:10,190 --> 00:01:13,324
Later, it also shows the page you are working
on.

20
00:01:13,324 --> 00:01:16,506
A browser tab is one page inside that window.

21
00:01:16,506 --> 00:01:19,629
Your file manager shows the files on your
computer.

22
00:01:19,629 --> 00:01:23,042
On Windows it is called File Explorer.

23
00:01:23,042 --> 00:01:25,991
On a Mac it is called Finder.

24
00:01:25,991 --> 00:01:28,824
Use it to find your downloaded practice
project.

25
00:01:28,824 --> 00:01:33,084
The terminal is a window where you type
instructions instead of clicking through

26
00:01:33,084 --> 00:01:37,357
menus. This learning path uses Claude Code in
the terminal.

27
00:01:37,357 --> 00:01:41,583
Claude Code has other interfaces too, but we
will stick with this one so the

28
00:01:41,583 --> 00:01:43,673
next lesson feels familiar.

29
00:01:43,673 --> 00:01:46,691
On Windows, our examples use PowerShell.

30
00:01:46,691 --> 00:01:49,106
On a Mac, they use Terminal.

31
00:01:49,106 --> 00:01:53,007
You do not need to understand everything
already written in that window.

32
00:01:53,007 --> 00:01:57,767
The practice asks you to choose the right
window for a few everyday actions.

33
00:01:57,767 --> 00:02:02,864
Finding a file, asking Claude for a change,
and looking at the result are different

34
00:02:02,864 --> 00:02:07,252
jobs. Knowing where each job happens removes
a lot of confusion.

35
00:02:07,267 --> 00:02:09,624
A file holds information.

36
00:02:09,624 --> 00:02:12,561
A folder keeps related files together.

37
00:02:12,561 --> 00:02:16,776
When we say project, we mean the folder of
files we are working on.

38
00:02:16,776 --> 00:02:21,129
Our download is a ZIP file, which is a
package containing those files.

39
00:02:21,129 --> 00:02:24,577
Extract means unpack that package into a
normal folder.

40
00:02:24,577 --> 00:02:27,933
On Windows, right-click the ZIP and choose
Extract All.

41
00:02:27,933 --> 00:02:30,417
On a Mac, double-click the ZIP.

42
00:02:30,417 --> 00:02:33,076
Then open the resulting reading list starter
folder.

43
00:02:33,076 --> 00:02:36,361
Work in that extracted folder, not the
compressed ZIP.

44
00:02:36,361 --> 00:02:40,820
Inside, index dot html is the page to open in
your browser.

45
00:02:40,820 --> 00:02:44,349
Styles dot c s s describes how the page
looks.

46
00:02:44,349 --> 00:02:47,356
App dot j s contains its behavior.

47
00:02:47,356 --> 00:02:49,806
The readme is a short note about the project.

48
00:02:49,806 --> 00:02:53,335
These names are labels to recognize, not a
spelling test.

49
00:02:53,335 --> 00:02:56,969
Double-click index dot html to see the
reading list.

50
00:02:56,969 --> 00:03:00,916
If an editor opens instead, use Open with and
choose your browser.

51
00:03:00,916 --> 00:03:04,063
Opening the page this way does not publish it
online.

52
00:03:04,063 --> 00:03:06,431
You are viewing a file on your own computer.

53
00:03:06,431 --> 00:03:10,575
The practice lets you rehearse unpacking and
opening it before you try the real

54
00:03:10,575 --> 00:03:11,400
download.

55
00:03:11,433 --> 00:03:15,508
The terminal may look unfamiliar, but we only
need two ideas for now.

56
00:03:15,508 --> 00:03:19,618
A folder path is an address that tells the
computer where a folder lives.

57
00:03:19,618 --> 00:03:22,137
The letters c d mean change directory.

58
00:03:22,137 --> 00:03:24,204
Directory is another word for folder.

59
00:03:24,204 --> 00:03:28,604
Type c d, a space, and the folder address in
quotes, then press Enter.

60
00:03:28,604 --> 00:03:31,378
The quotes keep an address with spaces
together.

61
00:03:31,378 --> 00:03:34,734
In this practice, use the example address
shown on screen.

62
00:03:34,734 --> 00:03:37,253
On your computer, the address will be
different.

63
00:03:37,253 --> 00:03:41,154
You can see the current folder in the example
prompt after the command runs.

64
00:03:41,154 --> 00:03:44,672
A prompt is the place where the terminal
waits for your next instruction.

65
00:03:44,672 --> 00:03:48,793
After Claude Code is installed, typing claude
and pressing Enter starts it in

66
00:03:48,793 --> 00:03:52,950
the current folder. The first launch may open
a browser for sign-in and ask

67
00:03:52,950 --> 00:03:54,505
about trusting the project.

68
00:03:54,505 --> 00:03:56,618
The next lesson covers that setup.

69
00:03:56,618 --> 00:04:00,136
Once Claude is ready, you can write an
ordinary sentence describing what you

70
00:04:00,136 --> 00:04:03,131
want. A setup command goes to the computer.

71
00:04:03,131 --> 00:04:06,046
Your request goes to Claude.

72
00:04:06,046 --> 00:04:09,122
If something fails, stop and read the
message.

73
00:04:09,122 --> 00:04:13,313
Copy the exact error when asking for help; do
not keep pasting commands you

74
00:04:13,313 --> 00:04:14,544
do not understand.

75
00:04:14,567 --> 00:04:18,015
Here is a request you can check without
knowing any code.

76
00:04:18,015 --> 00:04:21,928
Change the heading from Weekend reading to My
reading list.

77
00:04:21,928 --> 00:04:24,203
Keep the books and design the same.

78
00:04:24,203 --> 00:04:27,489
Explain which file you would change before
editing.

79
00:04:27,489 --> 00:04:31,657
That gives Claude a small task and tells it
what to leave alone.

80
00:04:31,657 --> 00:04:33,399
Read the proposed action.

81
00:04:33,399 --> 00:04:38,136
In our example, it is one heading in index
dot html.

82
00:04:38,136 --> 00:04:41,665
A permission request asks whether an action
may go ahead.

83
00:04:41,665 --> 00:04:46,553
The real wording depends on your settings, so
do not memorize a button position.

84
00:04:46,553 --> 00:04:49,165
Check that the action matches your request.

85
00:04:49,165 --> 00:04:52,439
If you are unsure, ask for an explanation.

86
00:04:52,439 --> 00:04:57,199
A heading change does not call for deleting
the project or publishing a website.

87
00:04:57,199 --> 00:05:02,238
In the practice, approve the small edit, then
open the browser preview and refresh

88
00:05:02,238 --> 00:05:06,325
it. You should see My reading list above the
same books.

89
00:05:06,325 --> 00:05:09,112
That visible comparison is your check.

90
00:05:09,112 --> 00:05:13,697
If the heading has not changed, or something
else looks different, tell Claude

91
00:05:13,697 --> 00:05:18,121
exactly what you see. You remain part of the
process.

92
00:05:18,121 --> 00:05:23,530
A message saying done is an invitation to
look, not proof that everything worked.

93
00:05:23,533 --> 00:05:26,772
Before moving on, check what feels familiar.

94
00:05:26,772 --> 00:05:30,627
Can you tell the browser, file manager, and
terminal apart?

95
00:05:30,627 --> 00:05:33,924
Do you know why the project should be an
extracted folder?

96
00:05:33,924 --> 00:05:37,593
Can you describe a small change and say what
success would look like?

97
00:05:37,593 --> 00:05:40,832
If one part still feels unclear, revisit it.

98
00:05:40,832 --> 00:05:44,396
Completing a practice screen does not mean
Claude Code is installed on your

99
00:05:44,396 --> 00:05:47,960
computer, and it does not make you a
programmer overnight.

100
00:05:47,960 --> 00:05:51,594
It means the next instructions now have
somewhere to land.

101
00:05:51,594 --> 00:05:56,111
For the real lesson, use a laptop or desktop
and have supported Claude Code

102
00:05:56,111 --> 00:06:00,662
account access. Check the official account
options linked in this lesson.

103
00:06:00,662 --> 00:06:04,214
Keep the practice project separate from files
you care about.

104
00:06:04,214 --> 00:06:07,546
The next lesson is called Your first session.

105
00:06:07,546 --> 00:06:12,167
Start at its beginning to learn the workflow,
or choose Open your first project

106
00:06:12,167 --> 00:06:14,454
when you are ready for installation.

107
00:06:14,454 --> 00:06:16,939
You will hear more technical words there.

108
00:06:16,939 --> 00:06:21,652
Ask for plain-language explanations and take
one action at a time.

109
00:06:21,652 --> 00:06:26,459
The habit is simple: say what you want,
understand the proposed action, and

110
00:06:26,459 --> 00:06:30,685
look at the result. That is enough to take
the next small step.
