This is a short presentation on what git is, how to use it to create a repository and start collaborating with coders.

1. Git basics
A
beginner’s
guide

3. ❏ Become familiar with the git workflow and basic commands.
❏ You have access to all versions of all files in Git repository at any time, it’s almost
impossible to lose any part of a code.
❏ But even if you are not convinced after this presentation to use it for your daily
work , at least knowing the basics will help you communicate better with the
developers in your team.
❏ It is not only for developers a great source code management tool. It can be used also by
designers and product managers to keep track of different versions of their work.

4. Agenda
❏ What is git?
❏ How does git work?
❏ Workflow - Basic commands
❏ Basic setup for your project
❏ Branching and Merging
❏ Review the Changes of your
Teammates

5. What is git ?
❏ Version Control tool. People can keep track of changes in the directory and recall different versions.
❏ Collaboration tool between multiple authors. Git keeps tracks of who, when and why does changes.
❏ Distributed VCS. Server has the master repo* , but you have a copy on your local machine and you can
run everything offline ( not pull & push from remote)
❏ Git and Gitlab are not the same!
* repository: A directory where Git has been initialized to start version controlling your files.

6. It is not the only Version Control tool ( Subversion, Mercurial )

7. Git workflow
❏ Push changes to remote.
$ git push remotename remotebranchname
❏ Make changes, then stage.
$ git add
❏ Obtain repository.
$ git init or $ git clone
Remote repository
Working directory
pull
Local repository
Stage
fetch
push
add
commitcheckout
❏ Commit changes to the local repository.
$ git commit -m “some changes”
❏ Fetch and checkout latest changes.
$ git fetch
$ git checkout

8. Time for action!

9. Git basic commands
❏ $ git push remotename remotebranch
❏ $ git merge featurename
❏ $ git checkout branchname
❏ $ git branch featurename
❏ $ git checkout -b featurename
❏ $ git pull || $ git fetch
❏ $ git commit -m “ commit message ”
❏ $ git add filename

10. Basic setup
❏ Login to git.ng.bluemix.net and go to your team’s gitlab project
❏ Create a new repository
❏ Follow the instructions and go to your terminal

11. Create a README.md file and do $ git status
$ git add README.md
$ git add -A or $ git add . will add all the latest changes of your local repo.
$ git commit -m “Initial commit”
$ git commit -am “Initial commit” will add all the latest changes and commit them
$ cd myFolder/thisGitProject/
$ git init
$ git config --global user.name "My Name"
$ git config --global user.email myEmail@example.com
In case you have already an existing folder
$ git remote add origin repositoryLinkOnGitlab.git
Basic setup

12. And finally….
$ git push -u origin master

13. Branches are a very smart way to isolate your work. You can experiment and
try out things without altering the dev or production code.
Branching and Merging
$ git branch featurename
You can change branch with:
$ git checkout branchname
or do both at once :
$ git checkout -b featurename

14. When you feature is ready, you can merge it with your
master branch.
Then, meeeergeeee
$ git merge featurename
First, checkout to the master branch
$ git checkout master
Branching and Merging

15. Code Reviews
❏ Crucial for shipping high quality code to production!

16. Thank you !
