-
-🎉🎉 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。
-
-### Installation
-
-    git clone https://github.com/RicterZ/nhentai
-    cd nhentai
-    python setup.py install
-    
-### Gentoo
-
-    layman -fa glicOne
-    sudo emerge net-misc/nhentai
-
-### Usage
-下载指定 id 列表的本子：
-```bash
-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
-```
-
-### 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
-`--nohtml`：nhentai Don't generate HTML
-`--cbz`：nhentai Generate Comic Book CBZ file
-
-### 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：  
-
-```bash
-NHENTAI=http://h.loli.club nhentai --id 123456
-```

+nHentai Mirror
+==============
+If you want to use a mirror, you should set up a reverse proxy of `nhentai.net` and `i.nhentai.net`.
+For example:
+
+.. code-block::
+
+    i.h.loli.club -> i.nhentai.net
+    i3.h.loli.club -> i3.nhentai.net
+    i5.h.loli.club -> i5.nhentai.net
+    i7.h.loli.club -> i7.nhentai.net
+    h.loli.club -> nhentai.net
+
+Set `NHENTAI` env var to your nhentai mirror.
+
+.. code-block:: bash
+
+    NHENTAI=https://h.loli.club nhentai --id 123456
