GIT repository tutorial 
------------------------------------------------------------------------------------ 
First open your account on fablab.io 
https://www.fablabs.io/signup 

Make sure about username, email ID and password. 

Install GIT in your Linux system with following commands: 
sudo apt-get install git -y
 
Check whether its installed or not: 
dpkg -s git 

Generation of new SSH key 
First do flush out all ssh keys from ssh folder. For this use command: 
cd ~/.ssh #navigate to .ssh folder 
rm * #delete everything present 

Check if still previous key is present, if yes then and also deleted all the keys from '.ssh' 
folder then restart your box. If not present proceed:
ssh-add -l # list out all the keys installed currently 

Generate the new ssh key as follows: 
ssh-keygen -t rsa -C "youremail@domain.com"
 
#replace with your email id, when prompted press enter to accept the defaults.
 
ssh-add ~/.ssh/id_rsa 
#this will add the key into ssh-agent
 
xclip -sel clip < ~/.ssh/id_rsa.pub 
#by-default it creates id_rsa file. if you have changed the defaults then replace that with 
this

IMPORTANT (discovered through research)
Now if you are setting up Ubuntu first time, it will prompt XCLIP- package not found.
Go to your settings->
Software update->
Click on all 4 options->
Unselect the lower option->
type sudo apt install xclip on terminal->
Now again put the key: xclip -sel clip < ~/.ssh/id_rsa.pub->
Now run this to ensure client is working or not: eval "$(ssh-agent -s)" It will show the agend pid (four digit)

Go to git.fabacademy.org -> sign in with FABLAB. Log in with fablab.io user credentials.
 
Once logged in go to the profile preferences, and look out for ssh keys section, open that 
section.

Then click on green colored 'Add Key' button and paste the key into the text-box provided and enter the title for your key, it can be anything but by-default it takes as you email id. 

-cat ~/.ssh/id_rsa.pub and Paste the ssh key from your account

Now run this to ensure client is working or not:
eval "$(ssh-agent -s)" 

Let's try to get the data from our repository. To clone the repository you can choose your 
favorite folder, I'll be using my home folder to clone the repository:
cd ~/ #this will take terminal to your Home directory 
git clone git@git.fabacademy.org:fabacademy2017/fablabvigyanashram.git 

You will find 'fablabvigyanashram' folder inside home directory 
Let's configure the git, use the username and the email id that you've used in the previous 
step to sign up into the account.:
cd ~/fablabvigyanashram 
#replace this with your repository folder 
git config --global user.name "yourname" 
git config --global user.email "youremail" 
git config --global push.default simple 

Now make all the necessary changes that you want to see inside 'fablab vigyan ashram’ 
folder.

Now, open the Terminal and execute the following commands :
cd ~/fablabvigyanashram 
git pull 
git add --all 
# add your changes 
git commit -m "message" 
# message which will identify user & purpose of commit 
git push 
# uploading process will start now! 
Follow above sequence for every PUSH and PULL of repo.a
