+
+## Build
+
+1. Pull docker image from repository:
+
+    ```
+    $ docker pull alexkolosovtelinksemi/chip-build-telink:latest
+    ```
+
+1. Run docker container:
+
+    ```
+    $ docker run -it -v ${CHIP_BASE}:/root/chip alexkolosovtelinksemi/chip-build-telink:latest
+    ```
+
+    here `${CHIP_BASE}` is directory which contains CHIP repo files **!!!Pay
+    attention that OUTPUT_DIR should conatins ABSOLUTE path to output dir**
+
+1. Run build script:
+    ```
+    cd /root/chip/scripts/examples && ./telink_example.sh
+    ```
+1. Exit docker container and collect build artifacts. Firmware binary would be
+   located in
+   **\${CHIP_BASE}/examples/lighting-app/telink/build/tlsr9518adk80d/zephyr/zephyr.bin**
+
+## Flash
+
+### Presetup
+
+To make `west flash` command works following steps should be performed just
+once:
+
+1. Download toolchain:
+    ```
+    $ wget http://wiki.telink-semi.cn/tools_and_sdk/Tools/IDE/telink_riscv_linux_toolchain.zip
+    $ unzip telink_riscv_linux_toolchain.zip
+    ```
+1. Add TELINK_TOOLCHAIN_BASE variable to environment:
+    ```
+    $ export TELINK_TOOLCHAIN_BASE=${PATH_TO_TOOLCHAIN}
+    ```
+1. Setup dependencies:
+
+    ```
+    $ sudo dpkg --add-architecture i386
+    $ sudo apt-get update
+    $ sudo apt-get install -y libc6:i386 libncurses5:i386 libstdc++6:i386
+    ```
+
+### Flashing
+
+1. Go to example directory and flash board with west command
+    ```
+    $ cd ${TELINK_LIGHTING_EXAMPLE_DIR} && west flash
+    ```
+
+## Border Router
+
+### Build
+
+Use following manual to build your own border router:
+https://openthread.io/guides/border-router/build Pay attention that border
+router should be configured as Access Point i.e next command should be executed
+in step 3:
+
+```
+$ BORDER_ROUTING=0 NETWORK_MANAGER=1 ./script/setup
+```
+
+### Setup IPv6
+
+Pay attention that border router shoud be configured as IPv6 access point.
+
+1. To do so perform the following command:
+    ```
+    ip -6 addr add 2001:db8:1::1/64 dev wlan0
+    ```
+2. Add following lines in **/etc/dnsmasq.conf** file:
+    ```
+    enable-ra
+    dhcp-range=2001:db8:1::, ra-only, 64, 12h
+    ```
+
+### Config network
+
+Use [Web GUI](https://openthread.io/guides/border-router/web-gui) to config
+Thread network **tlsr9518adk80d** board supports only static comissioning with
+predefined Thread credentials shown in table below:
+
+| Item                   |              Value               |

+| Passphrase             |              123456              |
+| Master Key             | 00112233445566778899aabbccddeeff |
+| Channel                |                15                |
+| On-Mesh Prefix         |            fd11:22::             |
+
+## Usage
+
+### UART
+
+To get output from device, connect UART to following pins:
+
+| Name | Pin                           |
+| :--: | :---------------------------- |
+|  RX  | PB3 (pin 17 of J34 connector) |
+|  TX  | PB2 (pin 16 of J34 connector) |
+| GND  | GND                           |
+
+### Buttons
+
+The following buttons are available on **tlsr9518adk80d** board:
+
+| Name     | Function         | Description                                                                                           |
+| :------- | :--------------- | :---------------------------------------------------------------------------------------------------- |
+| Button 1 | Factory reset    | Perform factory reset to forget currently commissioned Thread network and back to uncommisioned state |
+| Button 2 | Lighting control | Manually triggers the lighting state                                                                  |
+| Button 3 | Thread start     | Comission thread with static credentials and enables the Thread on device                             |
+
+### LEDs

+
+**Blue** LED shows current state of lightbulb
+
+### Check connection
+
+1. With your client device (PC, Laptop etc.) connect to BorderRouterAP WiFi
+2. Press Button 3 on **tlsr9518adk80d** board and wait till it joins to Thread
+   network
+3. Find ajusted IPv6 address in UART output of **tlsr9518adk80d**
+4. Perform following command on your client device:
+    ```
+    ping -6 ${IP_ADDRESS_OF_CHIP_DEVICE}
+    ```
+    here `${IP_ADDRESS_OF_CHIP_DEVICE}` is address which you got from UART
+    output of **tlsr9518adk80d** board If everything is ok then `ping` command
+    should perform transactions without losses
+
+### CHIP tool commands
+
+1. Build
+   [chip-tool cli](https://github.com/project-chip/connectedhomeip/blob/master/examples/chip-tool/README.md)
+1. Pair with device
+
+    ```
+    ${CHIP_TOOL_DIR}/chip-tool pairing bypass ${IP_ADDRESS_OF_CHIP_DEVICE} 11097
+    ```
+
+    here:
+
+    - `${IP_ADDRESS_OF_CHIP_DEVICE}` is IPv6 address of CHIP device
+    - **11097** is standart CHIP TCP port
+
+1. Switch on the light:
+
+    ```
+    ${CHIP_TOOL_DIR}/chip-tool onoff on 1
+    ```
+
+    here:
+
+    - **onoff** is name of cluster
+    - **on** command to the cluster
+    - **1** ID of endpoint
+
+1. Switch off the light:
+
+    ```
+    ${CHIP_TOOL_DIR}/chip-tool onoff off 1
+    ```
+
+    here:
+
+    - **onoff** is name of cluster
+    - **off** command to the cluster
+    - **1** ID of endpoint
+
+1. Read the light state:
+
+    ```
+    ${CHIP_TOOL_DIR}/chip-tool onoff read on-off 1
+    ```
+
+    here:
+
+    - **onoff** is name of cluster
+    - **read** command to the cluster
+    - **on-off** attribute to read
+    - **1** ID of endpoint
+
+1. Change brightness of light:
+
+    ```
+    ${CHIP_TOOL_DIR}/chip-tool levelcontrol move-to-level 32 0 0 0 1
+    ```
+
+    here:
+
+    - **levelcontrol** is name of cluster
+    - **move-to-level** command to the cluster
+    - **32** brightness value
+    - **0** transition time
+    - **0** option mask
+    - **0** option override
+    - **1** ID of endpoint
+
+1. Reag brightness level:
+    ```
+    ./chip-tool levelcontrol read current-level 1
+    ```
+    here:
+    - **levelcontrol** is name of cluster
+    - **read** command to the cluster
+    - **current-level** attribute to read
+    - **1** ID of endpoint
