-## Update Instructions
-
-We just moved Oh My Fish repository back to our own organization. Since then, you need to update your Oh My Fish remotes. A clean install is highly recommended for users of old Oh My Fish, and you can follow the steps described below:
-
-1. __BACKUP ALL YOUR CUSTOM STUFF__
-2. `mv ~/.config/fish/config{,_old}.fish`
-3. `rm -rf ~/.oh-my-fish`
-4. Do a [clean Oh My Fish install](#install)
-5. Copy all lines starting with `Plugin` and `Theme` from `~/.config/fish/config_old.fish`
-6. Paste them it into `$OMF_CONFIG/bundle` file. If it doesn't exist, create it
-7. Convert all `Plugin "name"` lines to `package name`
-8. Convert all `Theme "name"` lines to `theme name`
-9. `omf install`
-
-If you find any trouble in the upgrade process join us in [Slack](https://oh-my-fish-slack.herokuapp.com) and we will be happy to help.

-## 更新方法
-
-我们最近把Oh My Fish代码仓库移到了我们自己组织的帐号下。所以，你们也需要更新一下你们Oh My Fish代码仓的remote设置。对于Oh My Fish的早期用户，非常推荐你按照以下步骤干净地重新安装一次：
-
-1. __首先备份所有你自定义的东西__
-2. `mv ~/.config/fish/config{,_old}.fish`
-3. `rm -rf ~/.oh-my-fish`
-4. [重新安装Oh My Fish](#install)
-5. 复制文件`~/.config/fish/config_old.fish`中所有以`Plugin`和`Theme`开始的行
-6. 把它们粘贴到文件`$OMF_CONFIG/bundle`中。如果这个文件不存在，就自己创建一下
-7. 把所有`Plugin "name"`这样的行转换成`package name`这种形式，其中"name"是包名字
-8. 把所有`Theme "name"`这样的行转换成`theme name`这种形式，其中"name"是主题名字
-9. `omf install`
