learn Github in 3 Steps

Github - Repository, which save the files into the cloud

Git - Using users can actually retreive or save the data into the cloud

Download :
git-scm.com

check on command or terminal:
git --version

Configure:
git config --global user.name "ur name"
git config --global user.email "ur email"

Create folder:

mkdir folder_name  and go inside it - where u create the project or files

• Add any file  do the follwoing setps
• git init .                   // this is initialze the git
• git status                 // to check status
• git add index.html  //e.g index.html u created and want to upload into the git hub
• git commit -m "uploaded first file"
• git log   // to check ur log   - type q to quit from log
• // do same changes to the file and upload
• git status
• git diff index.html // can see the changes
• git add index.html 
• git status
• git commit -m "uploaded the upgraded file"

Branching:

master - Default branch

create develop branch:

•     git branch develop - to create branch e.g develop

•     git branch - check branches

•     git checkout develop - to switch from one barnch to another

•     do some changes in develop branch file

•     check master and develop branch

// create a branch if it does not exist, create new branch

• git checkout -b skill/new-skill
• IMPORTANT : so if u create this skill/new-skills branch inside the develop branch, then all the data of develop branch will be replicated into the skill/new-skills branch
• Now, once u added the new skills - just update it 
• git commit -am ""done with new skills"

Merging: 

As we above, suppose we have develop and skills branches. So to merge the child branch into the parent branch or vice versa.

• go to the branch in which u wanna merge by,
• git check out develop //here skills branch data will be transfered into the develop branch
• git merge feature/new-feature
• git log - to check the updated file in develop branch

GIT FLOW: Pluggin

It creates hierarchy of the project.

• install git-flow
• brew install git-flow // for mac
• sudo apt-get install git-flow
• git flow init -d - select branch for default, "master"
