+Overview
+********
+
+The PIC32CM JH01 Curiosity Nano+ Touch Evaluation Kit (EV29G58A) is
+a hardware platform that contains a PIC32CM5164JH01048 microcontroller (MCU).
+The Curiosity Nano+ Touch Evaluation Kit provides easy access
+to the MCU features and can develop custom applications.
+
+Hardware
+********
+
+- PIC32CM5164JH01048 MCU
+- Arm® Cortex®-M0+ based MCU
+- One yellow user LED
+- One mechanical user switch
+- One user touch button
+- CAN interface
+- LIN interface
+- USB for debugger
+
+  - Can be used for powering the board
+  - Must be used to program, or debug, the board
+- On-board nano debugger (nEDBG)
+
+  - One green power/status LED
+  - Programming and debugging
+  - Communications Device Class (CDC) virtual COM port
+  - One logic analyzer DGI GPIO
+  - The target device is programmed and debugged by the on-board Nano
+    debugger; no external programmer, or debugging tool, is required
+- Adjustable target voltage
+
+  - MIC5353 LDO regulator controlled by the on-board debugger
+  - 1.7V to 3.6V output voltage
+  - 500-mA maximum output current (limited by ambient
+    temperature and output voltage)
+
+Supported Features
+==================
+
+.. zephyr:board-supported-hw::
+
+Connections and IOs
+===================
+
+The `PIC32CM JH01 Curiosity Nano User Guide`_ has detailed information about board connections.
+
+Programming & Debugging
+***********************
+
+.. zephyr:board-supported-runners::
+
+Setting Up the Debug Interface
+==============================
+
+PyOCD Setup
+===========
+
+1. Install Device Pack
+
+   - Add support for the PIC32CM family devices using the following command:
+
+     .. code-block:: console
+
+        pyocd pack install pic32cm
+
+2. Verify Device Support
+
+   - Confirm that the target is recognized:
+
+     .. code-block:: console
+
+        pyocd list --targets
+
+   - You should see an entry similar to:
+
+     .. code-block:: text
+
+        pic32cm5164jh01048        Microchip                PIC32CM5164JH01048           PIC32CM-JH   pack
+
+3. Connect the Board
+
+   - Connect the DEBUG USB(J18) port on the board to your host machine.
+   - This connection **power up the board** and provides access to the **on-board Embedded Debugger (EDBG)**,
+     which enables programming and debugging of the target microcontroller through PyOCD.
+
+Building and Flashing the Application
+=====================================
+
+1. Build the Application
+
+   You can build a sample Zephyr application, such as **Blinky**, using the ``west`` tool.
+   Run the following commands from your Zephyr workspace:
+
+   .. code-block:: console
+
+      west build -b pic32cm_jh01_cnano -p -s samples/basic/blinky
+
+   This will build the Blinky application for the ``pic32cm_jh01_cnano`` board.
+
+2. Flash the Device
+
+   Once the build completes, flash the firmware using:
+
+   .. code-block:: console
+
+      west flash
+
+3. Observe the Result
+
+   After flashing, **LED1** on the board should start **blinking**, indicating that the
+   application is running successfully.
