- Okay, so, I have a whole playlist of videos

about Git and GitHub if you haven't,

if you don't know anything about Git and GitHub

you might want to go and look at some of those

as we'll assume basic knowledge.

What I'm going to show you is,

if you're on a new machine,

hopefully you might have set this up already,

but what if right now, for the first time,

you are using Git from the command line

and you also want to work with GitHub.

So I've actually already installed Git.

I can see that,

because I can type Git and it shows me a bunch of things,

it doesn't say Git is unknown,

but if you need to install Git,

you can just go to git-sem

and download the latest version for your

operating system and then back here.

I got all this crazy stuff open, let me close it.

I can start doing git commands,

like for example, if I make a directory,

that's make a directory, like new project

and I do cd new project and I say git init

that's how it actually makes a git repository

inside of a folder.

Oh, look at this, all of the sudden it says

look, git and master and I can do things like

git branch and somethings I don't like to

use the word master, I just use source or something

so I can say git branch source.

Okay actually, I haven't made any files, so it's not

going to let me make a the branch without

any files, so let me show you, this is a bit out

of scope but it's fine actually because

we can tie some things together, like for example

I'm going to say code dot.

It will open up this directory with Visual

Studio Code, then I'm going to make a new file

and I'm going to call it

sketch dot js because I'm

working on some Java script code.

I'm just going to put function setup in it and

hit save and look at this when I come back here

you can see now that the file is in there,

and look at this actually this changed

I think this is indicating something to me

like there's a new file or something.

So now I want to say git commit but

guess what, who's making that commit.

I haven't actually configured my, if I'm working with

git locally on my machine, I actually need to

configure who I am.

One thing I can do is, is type git config dash list

I believe, and this is all the various settings

of things that are like set up

I don't really care about that,

I just hit Q to get out of that.

What I need to do, and I'm just going

to look this up with git config user dot name

or user email, or user name

and this can be my name or whatever name I want to use.

You should probably tie this to your GitHub account.

Oh no it needs to be global, git config user name,

I want it to be global, I think if I do dash dash global

then I can say git config user dot email and

Daniel at the coding train dot com

dash dash global.

So this now, I've now set up git by the way.

If it's a fresh install you're going to

want to do this, with my information and

then I can do things like, I can say git status

and this is like the new untracked file

so I can say git add sketch dot js

and then I can commit it and maybe

what I want to do is say.

You know most people would just do this

git commit dash M for a short message

like make a new file and I could do that

but I'm being very long winded in this video

so what I'm actually going to do

is configure my editor.

So what I'm going to look for is configure

code editor with git or associate, I think

is the word I'm looking for, associate.

If I come here, basically this is what I need

git config dash dash global core.

I want this and I'm using code

and I think it's good like

to put this dash dash wait, meaning

it will wait for you to finish and now if I say

just git commit, it opened up this thing

in my editor, which I can now write my commit message.

New file and I can write my longer one like

dear diary,

I don't know what I am doing with my

life,

all the best, sheefmahn.

Alright and then once I close it, back here it's

done that and I don't know why I'm talking

about git branches but I can say

git branch source

and that made a new branch

like I can say git branch and it will list me

and I can hit Q to get out of that.

Git branch dash V, it's showing me more

information and I can say git checkout

source and now I'm in the source branch.

This is so useful if you know again, if you're new

to git you might not realize this but

know which branch you're in all the time,

having that reminder is incredibly useful.

I should also mention if I go back into

Visual Studio Code and I do things like add something

you know, create canvas two hundred, two hundred

you can see here there's ways, here you can see right

here this one comes up, so this is also

Visual Studio Code knows about git and it's showing

you things like this one change and if I click on

this here it's kind of showing you this

is the new line of code, that is the current change.

You can actually do all of your git stuff from

within Visual Studio Code yourself but, I tend to

do it here, something that is a little tricky is if

you want to not have to always

type in your username or password for GitHub

if you're about to send your code to GitHub

there is a way to configure that through a

SSH key, I think it makes sense to do that

in a separate video if people are interested in that.

The instructions are actually pretty good

on the GitHub website, SSH key GitHub.

If I go to this, generating a new SSH key, I

always am just following this exactly,

and then associating it with a particular laptop

and then that computer is automatically

logged in, you should probably use a passphrase

when it asks you, empty for no passphrase,

to be more secure.

Okay alright, so next, next up working with nodes

Oh, we're almost done.
