简单来说，Git 是一个管理你的「代码的历史记录」的工具。

github说白了就是一个【版本控制工具】

什么是 Github?

github是一个基于git的代码托管平台，付费用户可以建私人仓库，我们一般的免费用户只能使用公共仓库，也就是代码要公开。

Step 1. Create a Repository

A repository is usually used to organize a single project. Repositories can contain folders and files, images, videos, spreadsheets, and data sets – anything your project needs. We recommend including a README, or a file with information about your project.GitHub makes it easy to add one at the same time you create your new repository. It also offers other common options such as a license file.

Step 2. Create a Branch

Branching is the way to work on different versions of a repository at one time. By default your repository has one branch named masterwhich is considered to be the definitive branch. We use branches to experiment and make edits before committing them to master. When you create a branch off the master branch, you’re making a copy, or snapshot, of master as it was at that point in time.  If someone else made changes to the master branch while you were working on your branch, you could pull in those updates.

Step 3. Make and commit changes

Bravo! Now, you’re on the code view for your readme-editsbranch, which is a copy of master. Let’s make some edits.

On GitHub, saved changes are called commits. Each commit has an associated commit message, which is a description explaining why a particular change was made. Commit messages capture the history of your changes, so other contributors can understand what you’ve done and why.

These changes will be made to just the README file on your readme-edits branch, so now this branch contains content that’s different from master.

Step 4. Open a Pull Request

Nice edits! Now that you have changes in a branch off of master, you can open a pull request. Pull Requests are the heart of collaboration on GitHub. When you open a pull request, you’re proposing your changes and requesting that someone review and pull in your contribution and merge them into their branch. Pull requests show diffs, or differences, of the content from both branches. The changes, additions, and subtractions are shown in green and red.

As soon as you make a commit, you can open a pull request and start a discussion, even before the code is finished. By using GitHub’s @mention system in your pull request message, you can ask for feedback from specific people or teams, whether they’re down the hall or 10 time zones away.

You can even open pull requests in your own repository and merge them yourself. It’s a great way to learn the GitHub Flow before working on larger projects.

Step 5. Merge your Pull Request

In this final step, it’s time to bring your changes together – merging your readme-edits branch into the master branch.
