+# ENIG Protocol
+
+ENIG 프로토콜 통신 라이브러리
+
+**Explanation of the README Content:**
+
+1.  **Title and Overview:** Clearly states the purpose of the library.
+2.  **Key Components:** Explains the main building blocks:
+    *   `DeviceType` enum: Lists the device types.
+    *   `Packet` class: Describes the packet structure.
+    *   `EEProtocol` class: Explains its role in packet handling.
+3.  **Key Features:** Details the core functionalities of the `EEProtocol` class:
+    *   Packet creation.
+    *   Packet parsing.
+    *   Data reception.
+    *   Event-driven nature.
+    *   CRC16 calculation.
+4.  **Usage:** Provides code examples for:
+    *   Creating a packet.
+    *   Parsing a packet.
+    *   Processing received data.
+5.  **Error Handling:** Explains how the library handles invalid data and incomplete packets.
+6.  **Dependencies:** Lists any required frameworks or libraries.
+7.  **License:** Placeholder for the project's license.
+
+This README provides a comprehensive overview of the `ENIGProtocol` library, making it easy for other developers to understand and use it. I hope this is helpful!
