GitHub

GitHub is a web-based Git or Version Control Repository and Internet hosting service. It is mostly used for code. It offers all of the distributed version control and source code management (SCM) functionality of Git as well as adding its own features. It provides access control and several collaboration features such as bug tracking, feature requests, task management, and wikis for every project.

GitHub offers both plans for private and free repositories on the same account which are commonly used to host open-source software projects. As of April 2017, GitHub reports having almost 20 million users and 57 million repositories, making it the largest host of source code in the world.

GitHub has a mascot called Octocat, a cat with five tentacles and a human-like face.

Github flow

At GitHub, we use our products every day and have developed a workflow to collaborate on projects. To make it work for teams regardless of their size or technical expertise, we made sure each step in our workflow can be completed within a web-based interface.

1. Create a branch from the repository, Delete a branch from the repository.
2. Create, edit, rename, move, or [[#Delete file|delete] files.
3. Send a pull request from your branch with your proposed changes to kick off a discussion.
4. Make changes on your branch as needed. Your pull request will update automatically.
5. Merge the pull request once the branch is ready to be merged.
6. Tidy up your branches using the delete button in the pull request or on the branches page.

Create a branch

1. On GitHub, navigate to the main page of the repository.
2. Click the branch selector menu.
3. Type a unique name for your new branch.
4. Press Enter.

Delete a branch

1. On GitHub, navigate to the main page of the repository.
2. Above the list of files, click NUMBER branches.
3. Scroll to the branch that you want to delete, then click the trash-bin.

Create, edit, rename, move, or delete

On GitHub, navigate to the main page of the repository. In your repository, browse to the folder where you want to create a file. Above the file list, click Create new file. In the file name field, type the name and extension for the file. To create subdirectories, type the / directory separator. On the Edit new file tab, add content to the file. To review the new content, click Preview. At the bottom of the page, type a short, meaningful commit message that describes the change you made to the file. Below the commit message fields, decide whether to add your commit to the current branch or to a new branch. If your current branch is master, you should choose to create a new branch for your commit and then create a pull request. Click Propose new file. More...

GitHub Repo Files

GitHub encourages the creation of a number of standard files when adding a project or repository into the VCS. In every sense it is a good practise to do so.

Al files have the extension .md and uses the GitHub Wiki Markup Language MarkDown. Markdown is a way to style text on the web. You control the display of the document; formatting words as bold or italic, adding images, and creating lists are just a few of the things we can do with Markdown. Mostly, Markdown is just regular text with a few non-alphabetic characters thrown in, like # or *.

Markdown Syntax

The MarkDown syntax is explained on https://guides.github.com/features/mastering-markdown.

Text

• '*italic*' , italic by using 1 asterisk
• '**bold**', bold by using 2 asterisks
• [link to Google!](http://google.com) Link to Google

GitHub uses its own version of MarkDown named GitHub Flavored MarkDown (GFM), see https://guides.github.com/features/mastering-markdown/#GitHub-flavored-markdown for more.

The Changelog.md

Readme.md

READMEs generally follow one format in order to immediately orient developers to the most important aspects of your project .

• Project name: Your project’s name is the first thing people will see upon scrolling down to your README, and is included upon creation of your README file.
• Description: A description of your project follows. A good description is clear, short, and to the point. Describe the importance of your project, and what it does.
• Table of Contents: Optionally, include a table of contents in order to allow other people to quickly navigate especially long or detailed READMEs.
• Installation: Installation is the next section in an effective README. Tell other users how to install your project locally. Optionally, include a gif to make the process even more clear for other people.
• Usage: The next section is usage, in which you instruct other people on how to use your project after they’ve installed it. This would also be a good place to include screenshots of your project in action.
• Contributing: Larger projects often have sections on contributing to their project, in which contribution instructions are outlined. Sometimes, this is a separate file. If you have specific contribution preferences, explain them so that other developers know how to best contribute to your work. To learn more about how to help others contribute, check out the guide for (setting guidelines for repository contributors)[1].
• Credits: Include a section for credits in order to highlight and link to the authors of your project.
• License: Finally, include a section for the license of your project. For more information on choosing a license, check out GitHub’s licensing guide!
