-
-🎉🎉 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
-
-    git clone https://github.com/RicterZ/nhentai
-    cd nhentai
-    python setup.py install
-    
-
-### 用法
-+ 下载指定 id 列表的本子：
-
-
-    nhentai --id=123855,123866
-    
-
-+ 下载某关键词第一页的本子（不推荐）：
-
-
-    nhentai --search="tomori" --page=1 --download
-
-
-`-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/
-
-### 自建 nhentai 镜像
-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

+    cd nhentai
+    python setup.py install
+    
+=====================
+Installation (Gentoo)
+=====================
+.. code-block::
+
+    layman -fa glicOne
+    sudo emerge net-misc/nhentai
+
+=====
+Usage
+=====
+**IMPORTANT**: To bypass the nhentai frequency limit, you should use `--cookie` option to store your cookie.
+
+*The default download folder will be the path where you run the command (CLI path).*
+
+
+Set your nhentai cookie against captcha:
+
+.. code-block:: bash
+
+    nhentai --cookie "YOUR COOKIE FROM nhentai.net"
+
+Download specified doujinshi:
+
+.. code-block:: bash
+
+    nhentai --id=123855,123866
+
+Download doujinshi with ids specified in a file (doujinshi ids split by line):
+
+.. code-block:: bash
+
+    nhentai --file=doujinshi.txt
+
+Search a keyword and download the first page:
+
+.. code-block:: bash
+
+    nhentai --search="tomori" --page=1 --download
+
+Download by tag name:
+
+.. code-block:: bash
+
+    nhentai --tag lolicon --download --page=2
+
+Download your favorites with delay:
+
+.. code-block:: bash
+
+    nhentai --favorites --download --delay 1
+
+Format output doujinshi folder name:
+
+.. code-block:: bash
+
+    nhentai --id 261100 --format '[%i]%s'
+
+Supported doujinshi folder formatter:
+
+- %i: Doujinshi id
+- %t: Doujinshi name
+- %s: Doujinshi subtitle (translated name)
+- %a: Doujinshi authors' name
+
+
+Other options:
+
+.. code-block::
+
+    Options:
+      # Operation options

+
+
+==============
+nHentai Mirror

+For example:
+
+.. code-block:: 
+
+    i.h.loli.club -> i.nhentai.net
+    h.loli.club -> nhentai.net
+
+Set `NHENTAI` env var to your nhentai mirror.
+
+.. code-block:: bash
+
+    NHENTAI=http://h.loli.club nhentai --id 123456
+
+
+.. image:: ./images/search.png?raw=true
+    :alt: nhentai
