 🎉🎉 nhentai 现在支持 Windows 啦！
 
 由于 [http://nhentai.net](http://nhentai.net) 下载下来的种子速度很慢，而且官方也提供在线观看本子的功能，所以可以利用本脚本下载本子。
-### 安装
+
+### Installation
 
     git clone https://github.com/RicterZ/nhentai
     cd nhentai
     python setup.py install
     
+### Gentoo
 
-### 用法
-+ 下载指定 id 列表的本子：
+    layman -fa glicOne
+    sudo emerge net-misc/nhentai
 
+### Usage
+下载指定 id 列表的本子：
+```bash
+nhentai --id=123855,123866
+```
 
-    nhentai --id=123855,123866
+下载某关键词第一页的本子：
+```bash
+nhentai --search="tomori" --page=1 --download
+```
 
+下载用户 favorites 内容：
+```bash
+nhentai --login "username:password" --download
+```
 
-+ 下载某关键词第一页的本子（不推荐）：
-
-
-    nhentai --search="tomori" --page=1 --download
-
+### Options
 
 `-t, --thread`：指定下载的线程数，最多为 10 线程。  
 `--path`：指定下载文件的输出路径，默认为当前目录。  
 `--timeout`：指定下载图片的超时时间，默认为 30 秒。  
 `--proxy`：指定下载的代理，例如: http://127.0.0.1:8080/
+`--login`：nhentai 账号的“用户名:密码”组合
 
-### 自建 nhentai 镜像
+### nHentai Mirror
 如果想用自建镜像下载 nhentai 的本子，需要搭建 nhentai.net 和 i.nhentai.net 的反向代理。  
 例如用 h.loli.club 来做反向代理的话，需要 h.loli.club 反代 nhentai.net，i.h.loli.club 反带 i.nhentai.net。  
 然后利用环境变量来下载：  
 
-    NHENTAI=http://h.loli.club nhentai --id 123456
-
+```bash
+NHENTAI=http://h.loli.club nhentai --id 123456
+```
