GitHub is a web-based version control and collaboration platform used by over 31 million users. It allows users to store code in online repositories and collaborate on projects. The document provides instructions on setting up a GitHub account, installing Git, creating and committing to repositories, opening pull requests to contribute to others' projects, forking repositories to contribute back to open source projects, and cloning repositories to work on code locally.

Get Your Git On
Let me ask you some questions first - Do you have any kind of coding project? (It might be simple Java / C++ / Python etc…) - Now, if someone asks you to share your code, how will you do it?
Here’s your solution: GitHub lets you upload all your project files in one particular place for sharing and collaboration
What is GitHub? - Founded in 2008 - Web based version control and source control management using git - 31m users; 100m repositories - Acquired by Microsoft on June 2018 for $7.5b

GitHub dictionary – Bare minimum - “repository” – a.k.a repos are big chunks of code that can be edited by GitHub members - “forked” – the term for code editing/changes - “pull request” – intimation sent to the original code writer requesting edit rights More here: https://help.github.com/articles/github-glossary/

Create a new branch - A branch is a snapshot of the base branch (master in this example) at a moment in time - You can make changes to the new branch without affecting the base branch, until you merge the branches
Create a README - Created with Markdown language (.md files) - GitHub version called GitHub Flavored Markdown - Preview changes to see what it looks like before committing
Commit changes to your GitHub repository - You can commit your changes from either panes - Give a good description of what you’ve done - Go back to the top-level repository to see your commit shown.
Commit changes to your GitHub repository - Switch back and forth between the master branch and your new branch to see README changes and compare them visually. - Click on the commit comment to open a side-by-side source code view
Open a pull request for your GitHub repo - Submitting a PR is the way you can contribute to open source projects that have a small number of committers. - When you make the changes locally first, committing to your local repo and pushing to the upstream repo (e.g. on GitHub) are separate steps.
Merge a pull request into your master - On main repo page, click the green “Compare & pull request” button. This time the exact pull request you want to submit will come up. - When told that the request has no conflicts, press the green “Merge pull request” button
Delete the merged branch - Feel free to delete the successfully merged branch, using the button to the right of the purple icon. - Consider adding a branch every time you start working on a feature, and deleting the working branch once it has been successfully merged into a production branch.
Clone a GitHub repo - In real life people mostly write code & docs on their own machines, not online. - Go to the code pane of the repo and click on the green “Clone or download” button. - We don’t want to download a Zip; instead, we want to clone the repo with Git or GitHub Desktop.
- If you installed GitHub Desktop, click on “Open in Desktop.” - Your GitHub Desktop would look something like the image below once the clone finished: - Click on the copy icon to the right of the URL for your repo and paste the URL into a console after the command git clone
Fork a GitHub repo - Search for popular repos from GitHub to contribute back. - Fork is the way to contribute to someone else’s open source project. - Once you’ve got a forked repo, not only can you treat it as your own, but you can also apply later commits from the upstream repo from which you created the fork, and submit pull requests back to the upstream repo.
