"And slowly github became the new facebook for coders where instead of posting pictures and life events people post code for projects and your fellow developers comment, request features and fork the code to suit there needs.Brian Doll, GitHub’s vice president of strategy says “If you look at the top 100 sites, you’ve got a handful of social sites, thirty flavors of Google with national footprints, a lot of media outlets — and GitHub”Github is a web-based Git repository hosting service that primarily offers distributed version control and source code management functionality of git. The development of the GitHub platform began on 1 October 2007. The site was launched in April 2008 by Tom Preston-Werner, Chris Wanstrath, and PJ Hyett after it had been made available for a few months prior to a beta release.When Chris and Tom started working on GitHub in late 2007, Git was largely unknown as a version control system. There were no commercial Git hosting options whatsoever. And so GitHub was created to provide developers the option to host code securely and manage commits to code in a proper manner.Soon the adoption of GitHub for managing opensource projects grew rapidly due to which paid git hosting became a viable option and paid subscriptions made the project profitable. The software that runs GitHub was written using Ruby on Rails and Erlang.Here are some interesting facts about GitHub:Github was originally known as Logical Awesome LLC.As of May 2019, GitHub reports having over 37 million users and more than 100 million repositories (including at least 28 million public repositories), making it the largest host of source code in the world.The trademark mascot of Github is called Octocat, a personified cat with octopus limbs portrayed in manga style.

Specifically, Git is a distributed version control system, which means that the entire codebase and history are available on every developer’s computer, which allows for easy branching and merging. Why use something like Git? Say you and a coworker are both updating pages on the same website. You make your changes, save them, and upload them back to the website. So far, so good. The problem comes when your coworker is working on the same page as you at the same time. One of you is about to have your work overwritten and erased. A version control application like Git keeps that from happening. You and your coworker can each upload your revisions to the same page, and Git will save two copies. Later, you can merge your changes together without losing any work along the way. You can even revert to an earlier version at any time because Git keeps a “snapshot” of every change ever made. <h3>Terms used while working with Git:</h3> There are a few words I’m going to use repeatedly, none of which I’d heard before I started learning. Here are the big ones: Command Line:&nbsp;The computer program we use to input Git commands. On a Mac, it’s called Terminal. On a PC, it’s a non-native program that you download when you download Git for the first time (we’ll do that in the next section). In both cases, you type text-based commands, known as prompts, into the screen, instead of using a mouse. Repository:&nbsp;A directory or storage space where your projects can live. Sometimes GitHub users shorten this to “repo.” It can be local to a folder on your computer, or it can be a storage space on GitHub or another online host. You can keep code files, text files, image files, you name it, inside a repository. Version Control:&nbsp;Basically, the purpose of Git was designed to serve. When you have a Microsoft Word file, you either overwrite every saved file with a new saves, or you save multiple versions. With Git, you don’t have to. It keeps “snapshots” of every point in time in the project’s history, so you can never lose or overwrite it. Commit:&nbsp;This is the command that gives Git its power. When you commit, you are taking a “snapshot” of your repository at that point in time, giving you a checkpoint to which you can reevaluate or restore your project to any previous state. Branch:&nbsp;How do multiple people work on a project at the same time without Git getting them confused? Usually, they “branch off” of the main project with their own versions full of changes they themselves have made. After they’re done, it’s time to “merge” that branch back with the “master,” the main directory of the project. <h3>Git-Specific Commands:</h3> Since Git was designed with a big project like Linux in mind, there are a lot of Git commands. However, to use the basics of Git, you’ll only need to know a few terms. They all begin the same way, with the word “git.” git init: Initializes a new Git repository. Until you run this command inside a repository or directory, it’s just a regular folder. Only after you input this does it accept further Git commands. git config: Short for “configure,” this is most useful when you’re setting up Git for the first time. git help: Forgot a command? Type this into the command line to bring up the 21 most common git commands. You can also be more specific and type “git help init” or another term to figure out how to use and configure a specific git command. git status: Check the status of your repository. See which files are inside it, which changes still need to be committed, and which branch of the repository you’re currently working on. git add: This does not add new files to your repository. Instead, it brings new files to Git’s attention. After you add files, they’re included in Git’s “snapshots” of the repository. git commit: Git’s most important command. After you make any sort of change, you input this in order to take a “snapshot” of the repository. Usually, it goes git commit -m “Message here.” The -m indicates that the following section of the command should be read as a message. git branch: Working with multiple collaborators and want to make changes on your own? This command will let you build a new branch, or timeline of commits, of changes and file additions that are completely your own. Your title goes after the command. If you wanted a new branch called “cats,” you’d type git branch cats. git checkout: Literally allows you to “check out” a repository that you are not currently inside. This is a navigational command that lets you move to the repository you want to check. You can use this command as git checkout master to look at the master branch, or git checkout cats to look at another branch. git merge: When you’re done working on a branch, you can merge your changes back to the master branch, which is visible to all collaborators. git merge cats would take all the changes you made to the “cats” branch and add them to the master. git push: If you’re working on your local computer, and want your commits to be visible online on GitHub as well, you “push” the changes up to GitHub with this command. git pull: If you’re working on your local computer and want the most up-to-date version of your repository to work with, you “pull” the changes down from GitHub with this command. <h3>So What Is GitHub, Then?</h3> The problem with Git is that it’s so ancient that we have to use the command line — or Terminal if you’re a Mac user — in order to access it, typing in snippets of code like ’90s hackers. This can be a difficult proposition for modern computer users. That’s where GitHub comes in.GitHub is a for-profit company that offers a cloud-based Git repository hosting service. Essentially, it makes it a lot easier for individuals and teams to use Git for version control and collaboration. GitHub’s interface is user-friendly enough so even novice coders can take advantage of Git. Without GitHub, using Git generally requires a bit more technical savvy and use of the command line.GitHub is so user-friendly, though, that some people even use GitHub to manage other types of projects -like writing books. Additionally, anyone can sign up and host a public code repository for free, which makes GitHub especially popular with open-source projects. As a company, GitHub makes money by selling hosted private code repositories, as well as other business-focused plans that make it easier for organizations to manage team members and security. GitHub makes Git easier to use in two ways. First, if you download the GitHub software to your computer, it provides a visual interface to help you manage your version-controlled projects locally. Second, creating an account on GitHub.com brings your version-controlled projects to the Web, and ties in social network feature for good measure. You can browse other GitHub users’ projects, and even download copies for yourself to alter and learn from. Other users can do the same with your public projects, and even spot errors and suggest fixes. Either way, no data is lost because Git saves a “snapshot” of every change. While it’s possible to use GitHub without learning Git, there’s a big difference between using and understanding. Before I figured out much about Git I used GitHub, I didn’t really use git much. After being familiar with the commands and working I started using Git. <h3>Setting Up GitHub And Git For The First Time:</h3> First, you’ll need to sign up for an account on GitHub.com. It’s as simple as signing up for any other social network. Keep the email you picked. You could stop there and GitHub would work fine. But if you want to work on your project on your local computer, you need to have Git installed. In fact, GitHub won’t work on your local computer if you don’t install Git. Install Git for Windows, Mac or Linux as needed. You can download GitHub Desktop for Windows, Mac or Linux. Now it’s time to go over to the command line. On Windows, that means starting the Git Bash app you just installed, and on OS X, it’s regular old Terminal. It’s time to introduce yourself to Git. Type in the following code: <pre class="ql-syntax" spellcheck="false">git config --global user.name "Your Name Here"
</pre> Of course, you’ll need to replace “Your Name Here” with your own name in quotations. It can be your legal name, your online handle, anything. Git doesn’t care, it just needs to know to whom to credit commits and future projects. Next, tell it your email and make sure it’s the same email you used when you signed up for a GitHub.com account just a moment ago. Do it like this: <pre class="ql-syntax" spellcheck="false">git config --global user.email "your_email@youremail.com"
</pre> That’s all you need to do to get started using Git on your computer. However, since you did set up a GitHub.com account, it’s likely you don’t just want to manage your project locally, but also online. If you want you can also set up Git so it doesn’t ask you to log in to your GitHub.com account every time you want to talk to it. <h3>Creating Your Online Repository:</h3> Now that you’re all set up, it’s time to create a place for your project to life. Both Git and GitHub refer to this as a repository, or “repo” for short, a digital directory or storage space where you can access your project, its files, and all the versions of its files that Git saves. Go back to GitHub.com and click the tiny book icon next to your username. Or, go to the new repository page if all the icons look the same. Give your repository a short, memorable name. Go ahead and make it public; why hide your attempt to learn GitHub? Don’t worry about clicking the checkbox next to “Initialize this repository with a README.” A Readme file is usually a text file that explains a bit about the project. But we can make our own Readme file locally for practice. Click the green “Create Repository” button and you’re set. You now have an online space for your project to live in. <h3>Create Your Local Repository:</h3> So we just made a space for your project to live online, but that’s not where you’ll be working on it. The bulk of your work is going to be done on your computer. So we need to actually mirror that repository we just made as a local directory. This is where we do some heavy command line typing. First type: <pre class="ql-syntax" spellcheck="false">mkdir ~/MyProject
</pre>mkdir is short for make directory. It’s not actually a Git command, but a general navigational command from the time before visual computer interfaces. The ~/ ensures that we’re building the repository at the top level of your computer’s file structure, instead of stuck inside some other directory that would be hard to find later. Actually, if you type ~/ into your browser window, it’ll bring up your local computer’s top directory. Also, notice that I called it MyProject, the very same name I called my GitHub repository that we made earlier. Keep your name consistent, too. Next, type: <pre class="ql-syntax" spellcheck="false">cd ~/MyProject
</pre>cd stands for change directory, and it’s also a navigational command. We just made a directory, and now we want to switch over to that directory and go inside it. Once we type this command, we are transported inside MyProject. Now we’re finally using a Git command. For your next line, type: <pre class="ql-syntax" spellcheck="false">git init
</pre>You know you’re using a Git command because it always begins with git. init stands for “initialize.” Remember how the previous two commands we typed were general command-line terms? When we type this code in, it tells the computer to recognize this directory as a local Git repository. If you open up the folder, it won’t look any different, because this new Git directory is a hidden file inside the dedicated repository. However, your computer now realizes this directory is Git-ready, and you can start inputting Git commands. Now you’ve got both an online and a local repo for your project to live inside. <h3>Furthermore:</h3> You can learn about Web Hosting in Github, Creating a project board, Working with branches, Fork and so on….
