## Recommended Reading Path

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

<Steps>
  <Step title="Understand the Product">
    Start with the product structure, degrees of freedom, electrical interfaces, and package contents.

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

  <Step title="Before Power-On">
    Confirm the power, mechanical operation, environmental, and cable-protection requirements.

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

  <Step title="Connect and Run">
    Use the static IP, SDK connection, enable, and first-action sequence to run the hand.

    * [SDK Reference](/en/docs/wuji-hand/beta1/sdk-reference#connection) — Static IPs, SdkManager, and connection options
      * [Connect via SdkManager](/en/docs/wuji-hand/beta1/sdk-reference#connect-via-sdkmanager-recommended)
      * [ConnectOptions](/en/docs/wuji-hand/beta1/sdk-reference#connectoptions)
      * [Instance Attributes](/en/docs/wuji-hand/beta1/sdk-reference#instance-attributes)
    * [Run the First Motion](/en/docs/wuji-hand/beta1/sdk-reference#enable-/-disable-/-emergency-stop) — Enable the hand, then publish `joint_command`
    * [Wuji CLI Device Management](/en/docs/wuji-cli/device-management) — Scan devices and confirm the handshake and firmware version
  </Step>

  <Step title="Control and Diagnose">
    Move from whole-hand resources and joint numbering to diagnostics and log export.

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