+# Logger::Initialize
+
+```cpp
+void Initialize()
+```
+
+初始化日志系统。在首次使用日志功能前必须调用。初始化内部状态标志，确保日志系统已准备好工作。
+
+**注意：** 默认最小日志级别为 `Verbose`，所有日志分类默认启用，这些是类成员变量的默认值，不需要在此方法中设置。
+
+**复杂度：** O(1)
+
+**示例：**
+
+```cpp
+#include <XCEngine/Debug/Logger.h>
+
+int main() {
+    XCEngine::Debug::Logger::Get().Initialize();
+    XCEngine::Debug::Logger::Get().AddSink(std::make_unique<XCEngine::Debug::ConsoleLogSink>());
+    XCEngine::Debug::Logger::Get().Info(XCEngine::Debug::LogCategory::General, "Application started");
+    return 0;
+}
+```
