+
+## Usage
+
+```java
+/**
+ * Create a MinecraftServer object connected with the minecraft server running on port 25565 on host server.address.
+ * Caution:this method will try to connect to the determined server and get message that includes basic info,so this method
+ * will not return until receive the message.
+ */
+MinecraftServer minecraftServer=new MinecraftServer("server.address",25565);
+/**
+ * Call provided methods from interface to get specific info.
+ */
+System.out.println("version:name:"+minecraftServer.getVersionName()+" protocol:"+minecraftServer.getVersionProtocol());
+System.out.println("defaultDescription:color:"+minecraftServer.getDefaultDescriptionColor()+" text:"+minecraftServer.getDefaultDescriptionText());
+/**
+ * Get the list of extra description includes text and color.
+ * If your server does not have extra description(as usual),you can simply use getDefaultDescriptionColor() and getDefaultDescriptionText().
+ */
+IServerInfo.ExtraDescr[] extraDescrs=minecraftServer.getExtraDescription();
+for (IServerInfo.ExtraDescr extraDescr:extraDescrs){
+    System.out.println("extraDescription:color:"+extraDescr.color+" text:"+extraDescr.text);
+}
+System.out.println("players:max:"+minecraftServer.getMaxPlayer()+" online:"+minecraftServer.getOnlinePlayer());
+/**
+ * Get online player list.
+ */
+IServerInfo.Player[] players=minecraftServer.getPlayerList();
+for (IServerInfo.Player p:players){
+    System.out.println("player:name:"+p.name+" id:"+p.id);
+}
+/**
+ * Get server's icon(favicon) described in a Base64 way.
+ * Caution:sometime the packet with a very big Base64 data from server will cause a internal exception,you should try again.
+ */
+System.out.println("favicon:"+minecraftServer.getFavicon());

+
+## 版本
+
+最近的发行版:0.1,请参阅 Release 页面.
+
+## 摘要
+
+将此API以jar库的形式引入项目。此API提供了获取信息的接口，这些信息包括 服务器的版本 描述（MOTD） 在线玩家列表等能被官方客户端获取并展示在服务器列表的信息。
+
+## 用法
+
+```java
+/**
+ * 创建一个连接到运行在主机server.address上25565端口的Minecraft服务器的MinecraftServer对象
+ * 注意：此方法将会尝试连接到指定的服务器并获取包含基本信息的消息，因此此方法在获取到消息前不会返回，这是一个堵塞的方法
+ */
+MinecraftServer minecraftServer=new MinecraftServer("server.address",25565);
+/**
+ * 接下来，调用由接口提供的方法以获取特定的信息
+ */
+System.out.println("version:name:"+minecraftServer.getVersionName()+" protocol:"+minecraftServer.getVersionProtocol());
+System.out.println("defaultDescription:color:"+minecraftServer.getDefaultDescriptionColor()+" text:"+minecraftServer.getDefaultDescriptionText());
+/**
+ * 获取额外描述的列表，额外描述中包含了颜色和文字
+ * 如果你的服务器不含有额外描述（通常来说是这样），你可以简单地调用getDefaultDescriptionColor() 和 getDefaultDescriptionText()方法  
+ * 而不需要检查额外描述（extra description）
+ */
+IServerInfo.ExtraDescr[] extraDescrs=minecraftServer.getExtraDescription();
+for (IServerInfo.ExtraDescr extraDescr:extraDescrs){
+    System.out.println("extraDescription:color:"+extraDescr.color+" text:"+extraDescr.text);
+}
+/**
+ * 获取基本玩家信息
+ */
+        System.out.println("players:max:"+minecraftServer.getMaxPlayer()+" online:"+minecraftServer.getOnlinePlayer());
+/**
+ * 获取在线玩家列表
+ */
+IServerInfo.Player[] players=minecraftServer.getPlayerList();
+for (IServerInfo.Player p:players){
+    System.out.println("player:name:"+p.name+" id:"+p.id);
+}
+/**
+ * 获取以Base64编码的服务器图标（favicon）
+ * 注意：有些时候某个服务器包含了巨量的Base64编码的favicon，这会引起一些内部错误，请重新调用
+ */
+System.out.println("favicon:"+minecraftServer.getFavicon());
+```
