## Recommended reading path

Follow the stages from version identification and safety preparation through integration and maintenance.

<Steps titleSize="h3">
  <Step title="Know the Product">
    Confirm the device version, then review the structure, interfaces, and current capability boundaries.

    * [Version Identification and Compatibility](/en/docs/wuji-hand/latest/version-identification-and-compatibility) — Identify the device version and check hardware, firmware, SDK, and CLI compatibility
    * [Product Introduction](/en/docs/wuji-hand/latest/product-introduction) — Product overview, specifications, structure, interfaces, status light, and package contents
      * [Overview](/en/docs/wuji-hand/latest/product-introduction#overview)

      * [Back-of-Hand Status Light](/en/docs/wuji-hand/latest/product-introduction#back-of-hand-status-light)
  </Step>

  <Step title="Before You Power On">
    Review power, mechanical operation, environmental, and cable requirements before connecting the prototype.

    * [User Notice](/en/docs/wuji-hand/latest/user-notice) — Safety rules and current capability boundaries
      * [Power Safety](/en/docs/wuji-hand/latest/user-notice#power-safety)

      * [Cable and Flex-Cable Protection](/en/docs/wuji-hand/latest/user-notice#cable-and-flex-cable-protection)
  </Step>

  <Step title="Connect and Run">
    Follow Quick Start for simulation, device connection, the first safe motion, and firmware upgrade.

    * [Quick Start](/en/docs/wuji-hand/latest/quick-start) — Unboxing, software setup, real-device run, first motion, and cross-product teleoperation
      * [Simulation Check](/en/docs/wuji-hand/latest/quick-start#simulation-check)
      * [Step 4: Configure the Host Network Adapter](/en/docs/wuji-hand/latest/quick-start#step-4-configure-the-host-network-adapter)
      * [Step 6: Connect the Device](/en/docs/wuji-hand/latest/quick-start#step-6-connect-the-device)
      * [Step 9: Run Your First Safe Motion](/en/docs/wuji-hand/latest/quick-start#step-9-run-your-first-safe-motion)
      * [Step 11: Upgrade the Firmware](/en/docs/wuji-hand/latest/quick-start#step-11-upgrade-the-firmware)
    * [Wuji CLI Device Management](/en/docs/wuji-cli/device-management) — Scan devices, probe connectivity, and select a target without writing code
  </Step>

  <Step title="Integrate and Develop">
    Move from control conventions and calibration to hardware integration and SDK interfaces.

    * [Control Guide](/en/docs/wuji-hand/latest/control-guide) — Units, MIT control mode, joint table, and parameter safety limits
      * [MIT Control Mode](/en/docs/wuji-hand/latest/control-guide#mit-control-mode)
      * [Parameter Safety Limits](/en/docs/wuji-hand/latest/control-guide#parameter-safety-limits)
    * [Calibration and Configuration](/en/docs/wuji-hand/latest/calibration) — Joint origin, device parameters, IP configuration, and version requirements
    * [Hardware Integration](/en/docs/wuji-hand/latest/hardware-integration) — Wrist and palm interfaces, frames, models, power, and network
      * [Wrist Mounting Interface](/en/docs/wuji-hand/latest/hardware-integration#wrist-mounting-interface)
      * [Palm Mounting Interface](/en/docs/wuji-hand/latest/hardware-integration#palm-mounting-interface)
      * [Coordinate Frames and Models](/en/docs/wuji-hand/latest/hardware-integration#coordinate-frames-and-models)
      * [Power Supply](/en/docs/wuji-hand/latest/hardware-integration#power-supply)
      * [Network Configuration](/en/docs/wuji-hand/latest/hardware-integration#network-configuration)
    * [SDK Interface](/en/docs/wuji-hand/latest/sdk-reference/index) — Wuji Hand 2 data streams and control interfaces
      * [Joint Control](/en/docs/wuji-hand/latest/sdk-reference/joint-control)
      * [Effort and MIT](/en/docs/wuji-hand/latest/sdk-reference/effort-and-mit)
      * [IMU](/en/docs/wuji-hand/latest/sdk-reference/imu)
      * [Device Operations](/en/docs/wuji-hand/latest/sdk-reference/device-operations)
      * [Diagnostics](/en/docs/wuji-hand/latest/sdk-reference/diagnostics)
    * [SDK Practice](/en/docs/wuji-hand/latest/sdk-practice/index) — Runnable subscription, control, scanning, and log-export examples
