1.build过程
将Vno-Jekyll下载后，copy到<username>.github.io的仓库 root 目录下, 执行 bundle install安装好当前Jekyll的依赖。效果如下

Bundle complete! 2 Gemfile dependencies, 20 gems now installed.
Use `bundle info [gemname]` to see where a bundled gem is installed.
依赖安装完毕后执行jekyll serve就可以开启本地调试了：
EmptyWalker-2:github-site emptywalker$ jekyll serve

至此，将当前的代码push到仓库里就可以使用https://<username>.github.io访问主页了
问题描述
如果我直接在_post文件夹下添加YYYY-MM-DD-name.md文档，是需要执行jekyll serve，先生成对应的html，然后再push到master分支后，才能生效，如何在github page中自动生效
2. GitHub Pages is temporarily down for maintenance.
在访问GitHub Pages上部署的网站时，出现暂时维护的状态，不清楚是配置有问题还是真的在维护，这个维护时间多久？都不确定
答案：整个过程大约持续了半小时，恢复访问
3. 设置Jekyll的图片资源链接
参考官方文档,设置格式如下
其中site.url是表示网站的域名。可以自己在根目录添加assets/downloads文件夹来存储图片资源和可下载资源
