{
  "capabilities":
      [
        {
          "browserName": "*firefox",
          "maxInstances": 5,
          "seleniumProtocol": "Selenium"
        },
        {
          "browserName": "*googlechrome",
          "maxInstances": 5,
          "seleniumProtocol": "Selenium"
        },
        {
          "browserName": "*iexplore",
          "maxInstances": 1,
          "seleniumProtocol": "Selenium"
        },
        {
          "browserName": "firefox",
          "maxInstances": 5,
          "seleniumProtocol": "WebDriver"
        },
        {
          "browserName": "chrome",
          "maxInstances": 5,
          "seleniumProtocol": "WebDriver"
        },
        {
          "browserName": "internet explorer",
          "maxInstances": 1,
          "seleniumProtocol": "WebDriver"
        }
      ],

    }
  ],

...
"servlets": ["io.sterodium.extensions.node.SikuliExtensionServlet","io.sterodium.extensions.node.upload.FileUploadServlet","io.sterodium.extensions.node.download.FileDownloadServlet"]

}
