## Recommended Reading Path

Follow these stages to understand the product, prepare it safely, connect it, and diagnose it.

**1. Understand the Product**

Start with the product structure, degrees of freedom, electrical interfaces, and package contents.

* [Product Introduction](https://docs.wuji.tech/docs/en/wuji-hand/beta1/overview.md) — Specifications, structure, electrical characteristics, and package contents
  * [Overview](https://docs.wuji.tech/docs/en/wuji-hand/beta1/overview.md#overview)
  * [Specifications](https://docs.wuji.tech/docs/en/wuji-hand/beta1/overview.md#specifications)
  * [Mechanical Structure](https://docs.wuji.tech/docs/en/wuji-hand/beta1/overview.md#mechanical-structure)
  * [Communication and Power Interface](https://docs.wuji.tech/docs/en/wuji-hand/beta1/overview.md#communication-and-power-interface)
  * [Package Contents](https://docs.wuji.tech/docs/en/wuji-hand/beta1/overview.md#package-contents)

**2. Before Power-On**

Confirm the power, mechanical operation, environmental, and cable-protection requirements.

* [User Notice](https://docs.wuji.tech/docs/en/wuji-hand/beta1/user-notice.md) — Safety requirements before use
  * [Power Safety](https://docs.wuji.tech/docs/en/wuji-hand/beta1/user-notice.md#power-safety)
  * [Mechanical Operation Safety](https://docs.wuji.tech/docs/en/wuji-hand/beta1/user-notice.md#mechanical-operation-safety)
  * [Environmental Requirements](https://docs.wuji.tech/docs/en/wuji-hand/beta1/user-notice.md#environmental-requirements)
  * [Cable and Flex-Cable Protection](https://docs.wuji.tech/docs/en/wuji-hand/beta1/user-notice.md#cable-and-flex-cable-protection)
* [Usage Constraints](https://docs.wuji.tech/docs/en/wuji-hand/beta1/usage-constraints.md) — Capability boundaries and available behavior for the Beta stage

**3. Connect and Run**

Connect through ROS 2 or the SDK, check the state, then run the first motion.

* [ROS 2 Integration](https://docs.wuji.tech/docs/en/wuji-hand/beta1/ros2-integration.md) — Read state, control joints, and display the model in RViz through ROS 2
* [SDK Reference](https://docs.wuji.tech/docs/en/wuji-hand/beta1/sdk-reference.md#connection) — Static IPs, SdkManager, and connection options
  * [Connect via SdkManager](https://docs.wuji.tech/docs/en/wuji-hand/beta1/sdk-reference.md#connect-via-sdkmanager-recommended)
  * [ConnectOptions](https://docs.wuji.tech/docs/en/wuji-hand/beta1/sdk-reference.md#connectoptions)
  * [Instance Attributes](https://docs.wuji.tech/docs/en/wuji-hand/beta1/sdk-reference.md#instance-attributes)
* [Run the First Motion](https://docs.wuji.tech/docs/en/wuji-hand/beta1/sdk-reference.md#enable-/-disable-/-emergency-stop) — Enable the hand, then publish `joint_command`
* [Wuji CLI Device Management](https://docs.wuji.tech/docs/en/wuji-cli/latest/device-management.md) — Scan devices and confirm the handshake and firmware version

**4. Control and Diagnose**

Move from whole-hand resources and joint numbering to diagnostics and log export.

* [Hand-Level Resources](https://docs.wuji.tech/docs/en/wuji-hand/beta1/sdk-reference.md#hand-level-resources) — State, diagnostics, MIT parameters, and control actions
  * [Clear Fault](https://docs.wuji.tech/docs/en/wuji-hand/beta1/sdk-reference.md#clear_fault-exec)
  * [User Origin](https://docs.wuji.tech/docs/en/wuji-hand/beta1/sdk-reference.md#user-origin)
  * [Joint Traversal](https://docs.wuji.tech/docs/en/wuji-hand/beta1/sdk-reference.md#joint-traversal)
  * [Joint Numbering](https://docs.wuji.tech/docs/en/wuji-hand/beta1/sdk-reference.md#joint-numbering)
* [Data Subscription](https://docs.wuji.tech/docs/en/wuji-sdk/latest/data-subscription.md) — Async, sync, and callback receive modes
* [Flash Log Export](https://docs.wuji.tech/docs/en/wuji-hand/beta1/sdk-reference.md#flash-log-export-diagnostics) — Export device logs for diagnosis
* [Doctor](https://docs.wuji.tech/docs/en/wuji-cli/latest/doctor.md) — Check connectivity, versions, and permissions
