正如JB非常正确地指出的那样，在GitHub上，只要简单地按照说明进行操作就变得非常容易。

下面是登录时使用http://github.com/new在GitHub上设置新存储库后显示的说明示例。

Global setup:

 Set up Git:
  git config --global user.name "Name"
  git config --global user.email email@gmail.com


Next steps:

  mkdir audioscripts
  cd audioscripts
  git init
  touch README
  git add README
  git commit -m 'first commit'
  git remote add origin git@github.com:ktec/audioscripts.git
  git push -u origin master


Existing Git repository?

  cd existing_git_repo
  git remote add origin git@github.com:ktec/audioscripts.git
  git push -u origin master


Importing a Subversion repository?

  Check out the guide for step-by-step instructions.

再简单不过了!!

实际上，如果你选择在GitHub上创建一个空的repo，它会给你确切的指令，你几乎可以复制和粘贴到你的终端(在这个时间点):

…or create a new repository on the command line

echo "# ..." >> README.md
git init
git add README.md
git commit -m "first commit"
git remote add origin git@github.com:<user>/<repo>.git
git push -u origin master

当我尝试做皮特的步骤时，我在合并方面遇到了一些麻烦。这些是我最后的步骤。

Use your OS to delete the .git folder inside of the project folder that you want to commit. This will give you a clean slate to work with. This is also a good time to make a .gitignore file inside the project folder. This can be a copy of the .gitignore created when you created the repository on github.com. Doing this copy will avoid deleting it when you update the github.com repository. Open Git Bash and navigate to the folder you just deleted the .git folder from. Run git init. This sets up a local repository in the folder you're in. Run git remote add [alias] https://github.com/[gitUserName]/[RepoName].git. [alias] can be anything you want. The [alias] is meant to tie to the local repository, so the machine name works well for an [alias]. The URL can be found on github.com, along the top ensure that the HTTP button out of HTTP|SSH|Git Read-Only is clicked. The git:// URL didn't work for me. Run git pull [alias] master. This will update your local repository and avoid some merging conflicts. Run git add . Run git commit -m 'first code commit' Run git push [alias] master

我来这里是为了寻找一种简单的方法将现有的源文件添加到GitHub存储库中。我看到了@Pete完美完整的回答，心想“什么?!”一定有更简单的办法。”

这里有一个简单的方法，分为五个步骤(不需要控制台操作!)

如果你真的很赶时间，你可以读步骤3。其他的只是为了完整。

在GitHub网站上创建一个存储库。(我不会一步一步地给你讲解，以免侮辱你的智商。) 在本地克隆新的存储库。(你可以通过网站或桌面客户端软件来完成。) 在您的硬盘驱动器上找到新克隆的存储库，并像在普通目录中一样添加文件。 将更改同步回GitHub。 就是这样!

完成了!

其中一条评论提到了使用GitHub GUI，但它没有提供任何具体的使用帮助，并注意到大多数(如果不是所有的话)答案只在命令提示符下有用。

如果你想使用GitHub GUI，你可以按照以下步骤:

Click the "+" button and choose "Add Local Repository" Navigate to the directory with your existing code and click the "Add" button. You should now be prompted to "Create a new local Git repository here" so click the "Yes" button. Add your "Commit Summary" and "Extended description" as desired. By default, all of your files should selected with checkmarks already. Click the "Commit & Sync" button. Now you will be prompted to add the name and description of your project as well as which account to push it to (if you have multiple). Click the "Push Repository" button

在旋转GitHub图标后，您的源代码将属于本地存储库，并在您的GitHub帐户上推送/同步到远程存储库。所有这些都假设您之前已经设置了GitHub GUI、您的GitHub帐户和SSH密钥。
