+## Introduction
+
+ZIGGO is a `flexible`, `standard-compliant`, and `control-function-virtualized` TSN switch platform ready for **industrial control**, **automotive electronics**, and other **time-sensitive applications**.
+
+This is the document for the ZIGGO Device. (We also offer [ZIGGO-CaaS-Switch](https://github.com/Mobisense/Ziggo-CaaS-Switch) that comply with the IEEE 802.1 TSN standard.) Our Device supports testing all standards-compliant switches.
+
+## ZIGGO Open Platform
+
+![](figs/demo-app.png)
+
+The construction of the ZIGGO Open Platform consists of three levels: network device, management tools, and a Demo App:
+
+- The software and hardware projects, along with the development board startup [tutorial](/ZIGGO_WEB/device/getting-started/), provide instructions for setting up an individual network device.
+
+- The [CNC User Manual](docs/cnc-manual.md) and [Device User Manual](/ZIGGO_WEB/device/getting-started/) cover system configuration and management tools.
+
+- Lastly, we offer a comprehensive [Demo App building tutorial](/ZIGGO_WEB/device/testbed/) that instructs how to
+  collaboratively build a complete and functional Demo using network devices and
+  management tools.
+
+## Demo
+
+We provide a demonstration video of the TSN switch. It demonstrates the superior performance of the `ZIGGO-CaaS-Switch` compared to the normal switch.
+
+The left side of the picture is the ZYNQ development board we use, and the right side is the TSN display board we built.

+
+## Features
+
+* ZIGGO supports the simultaneous transmission of both `Information Technology (IT)` and `Operation Technology (OT)` data traffic with QoS guarantee.
+
+* ZIGGO complies with IEEE standards `802.1AS`, `Qav`, `Qbv`, and `Qcc`.
+
+* ZIGGO provides `Real-time` and `Deterministic` Ethernet transport
+
+  * ZIGGO achieve **Zero Packet Loss** , **Microsecond-level Latency** with **Nanosecond-level Jitter Gate Ability**.
+  * ZIGGO guarantee **Gigabit Throughput**.
+  * ZIGGO provide gate accuracy applicable to **All Ethernet Frame Sizes**.
+
+## Read before start
+
+Getting started with ZIGGO-CaaS-Switch/ZIGGO-Device is a ***pretty hard*** task. Users/developers need to have sufficient basic knowledge and be prepare to for a long periond of learning and debugging.
+
+Please refer to [basic_knowledge.md](/ZIGGO_WEB/device/basic_knowledge/) to check if you have ability to use ZIGGO competently. 
+
+## Getting Started
+
+Please refer to [required.md](/ZIGGO_WEB/device/require/)  to  get prepared.
+
+After that, please refer to [getting_started.md](/ZIGGO_WEB/device/getting-started/) for the build and run a single ZIGGO Device.
+
+## System Design
+
+ZIGGO is implemented on ZYNQ-7000 SoC and exploits ZYNQ's both hardware and software programmability. 
+
+![framework](figs/framework.jpg)
+
+We also provide more in-depth [documentation](/ZIGGO_WEB/device/system-design/) explaining specific design principles for ZIGGO Device.
+
+## Demo APP Tutorial
+
+We also provide a [testbed build document](/ZIGGO_WEB/device/testbed/) that allows you to build a real-time Ethernet system using the ZIGGO swtich and Device. 
+
+Through this platform, we can measure the `delay` and `jitter` of TSN time-critcial traffic, the switch's `gating capability`, `bandwidth guarantee` and `gating accuracy`. 
+
+Replacing ZIGGO CaaS switches with commercial TSN switches can also test its above capabilities.
