人靠衣装马靠鞍，hexo一样。hexo官网除了提供各种版本的维护之外，同时向用户提供了大量不同风格的主题，以jacman为例总结更换主题的操作。
下载主题
直接Git Bash命令行中输入命令：$ git clone https://github.com/wuchong/jacman.git themes/jacman（会再D:\tools\hexo\themes文件夹下生成一个jacman的文件夹）
修改配置文件
修改根目录下的_config.xml
修改hexo文件夹下_config.yml（根目录下的），内容如下（有注释，用Sublime Text(使用它的原因是默认是UTF-8编码，中文不会乱码)打开_config.yml文件，否则会乱码的）
注：
在每个参数的”：”后都要加一个空格修改网站相关信息;
