     Optionally, you can use the cmake function `create_esp_enc_img()` to encrypt
     the OTA image during the build process. Please find the usage below. This is
     also demonstrated in the `examples/lighting-app/esp32/main/CMakeLists.txt`
     file.
 
-        ```
-        create_esp_enc_img(${CMAKE_BINARY_DIR}/${CMAKE_PROJECT_NAME}.bin
