Anyone who completes this projects shows they can...

Fork and Clone a repo
understand git branching locally
properly use git commands such as status, add, commit and push
create pull requests (PR's) for code reviews

Introduction

In this guide you will learn the basics of working with Git and Github and also understand basic git workflow.

Project MVP is achieved by opening a PR requesting to merge your name branch into main branch.

Prerequisites

You should have git (Linux / Mac) or GitBash (Windows) installed and setup first before you continue on.

Make sure you follow this first time setup so that git knows who you are, if not git will ask you to set this up on your first commit

Git First Time Setup

The first thing you should do when you install Git is to set your user name and email address. This is important because every Git commit uses this information, and it’s immutably baked into the commits you start creating:

$ git config --global user.name "John Doe"
$ git config --global user.email johndoe@example.com

Instruction

Please fork and clone this repository
Create a new branch and name it with your name eg john-doe
Create a new "Hello World" project using your language of choice such as Python, Java, JavaScript, Ruby or even bash script.
View the status of the git repo, add your changes to staging, view the status of the repo again. Once happy with the status of the repo, commit your changes.
push your changes up into Github
Open a pull request (PR) setting your name branch as the branch to merge into your main branch

Git reference

Staging Changes

git add .

Add all changed files and folder, in the current folder you are in, into the staging area

NOTE: . (dot) represents the current directory / folder that you are in.

git add ./filename [file2, file3, ...]

Add individual file(s) to the staging area.

Commiting Changes

git commit -m "commit message"

# For multi line commmits
git commit -m "commit type: basic summary

details about the changes here"

Optoinal reading: Semantic Commits

When you commit code, you need to create a message, these messages are very useful for your self and others to understand changes that were made in the code at the specific point in time. This is really useful for when you want to undo changes you made in your project.

View Repo Status

git status

View the current state that your repo is in. Shows whats in staging, changes and other outstanding items.

Pushing Changes

# replace <branch> with your branch name eg. git push origin main
git push origin <branch>

Push code back up to Github in the specified branch.

Branching

# replace <branch-name> with a branch name eg. john-doe
git checkout -b <branch-name>

Create a new branch and move into it.

Viewing Branches

git branch

Shows local branches available along with current working branch.

git branch -av

Shows all branches in the repo both local and remote.

Moving Between Branches

git checkout <existing-branch>

Change your current working branch, to another branch that already exists

Git Log

git log

Show the history of the git repo (project)
