+# Kenaito Config Center C++ Client
+
+C++ client SDK for the Kenaito Config Center, suitable for C++11 and above.
+
+## Features
+
+- Fetch application configs from the config center
+- Periodic config sync
+- Config change callback listener
+- Local file cache (fallback when config center is unavailable)
+
+## Dependencies
+
+- C++11 or higher
+- libcurl
+- nlohmann/json (included in third_party directory)
+
+## Build
+
+```bash
+cd kenaito-conf-cpp-client
+mkdir build && cd build
+cmake ..
+make
+```
+
+## Usage
+
+```cpp
+#include <kenaito_conf/client.h>
+#include <iostream>
+
+int main() {
+    kenaito::Config config;
+    config.base_url = "http://localhost:8080";
+    config.app_name = "my-app";
+    config.env = "daily";
+    config.sync_interval = 10;
+    config.cache_dir = ".";
+
+    kenaito::Client client(config);
+
+    // Listen for config changes
+    client.on_change([](const std::map<std::string, std::string>& changed) {
+        std::cout << "Config changed:" << std::endl;
+        for (const auto& [k, v] : changed) {
+            std::cout << "  " << k << " = " << v << std::endl;
+        }
+    });
+
+    // Start client
+    if (!client.start()) {
+        std::cerr << "Failed to start config client" << std::endl;
+        return 1;
+    }
+
+    // Get config
+    std::string db_host = client.get("database.host");
+    std::cout << "database.host = " << db_host << std::endl;
+
+    // Get all configs
+    auto all = client.get_all();
+    for (const auto& [k, v] : all) {
+        std::cout << k << " = " << v << std::endl;
+    }
+
+    // Manual sync
+    client.sync_once();
+
+    // Stop
+    client.stop();
+
+    return 0;
+}
