GIT Tutorial

LET'S MAKE SOME GIT !

Step 1 : Install Git and create a Github account

I'm using Windows, so to install Git I just had to download it on git-scm.com. You can find on this page all the way to install Git according to the OS you're using.

Note that for this tutorial, we'll use Git on the command line only.

Then create a Github account. To do so, you can follow this tutorial on Wikihow. Note that Github public repositories are free of charge, but if you want private ones you have to pay for it.

What is Github ? It was founded in 2008 and it is the largest web-based git repository hosting service. It allows collaboration with anyone online and adds extra functionnalities on top of Git.

Step 2 : First time on Git ? Let's do the setup !

Open your terminal or command prompt. It is where you'll type in your command lines. I use Windows, as said earlier, and here are some ways to open it.

Now you have to type in those command lines to setup :

your identity	git config --global user.name "Your name"
your editor	git config --global core.editor <any code editor like vim, sublime, etc>
enable color in git	git config --global color.ui auto
checking your settings	git config --list

Okay, let's get to the real stuff now ! :)

Step 3 : Create a new repository

Create a new directory, open it and perform a Git init to create a new local git repository.

Step 4 : Get to know important Git commands

Get the status of your Git repo

git status

Add new file to staging area

git add <filename> git add * (will add all changes, without selection)

Commit your changes

git commit git commit -m "name your changes" (will name your commit)

Get Git commit history

git log

Send changes to your remote repository	git push origin master
Push to a branch other than 'master'	git push origin branch_name

Step 5 : Understanding branches

I don't use it on my website, but branching is the most important thing to understand when it comes to Git so that's why I'll explain it to you here. Here is an illustration so you can understand it better :

Git kinda works like a tree. There is the "master branch", which can be compared to the trunk of the tree. The "master branch" is the "default" branch when you create a repository.

And there are branches which are used to develop features isolated from each other, may they be little or big.
I created one on my repo as an exemple :

Create a branch

git branch new_branch_name

Switch to a different branch

git checkout other_branch_name

Create a new branch and checkout to that branch

git checkout -b new_branch_name

Show all the branches

git branch

Delete a branch

git branch -d branch_name
