+new InitConfig.Builder()
+    .setContext(context)
+    .setPrimaryServiceHost("httpdns-a.example.com")
+    .setBackupServiceHost("httpdns-b.example.com")
+    .setServicePort(443)
+    .setSecretKey("your-sign-secret")
+    .setEnableHttps(true)
+    .buildFor("app1f1ndpo9");
+```
+
+## 解析
+
+```java
+HTTPDNSResult result = httpDnsService.getHttpDnsResultForHostSyncNonBlocking(
+    "api.business.com",
+    RequestIpType.auto,
+    null,
+    null
+);
+```
+
+## 官方业务适配器
+
+```java
+HttpDnsHttpAdapter adapter = HttpDns.buildHttpClientAdapter(httpDnsService);
+HttpDnsAdapterResponse resp = adapter.execute(
+    new HttpDnsAdapterRequest("GET", "https://api.business.com/v1/ping")
+);
