Additionally, update README with new config option:

        "ignoreSSLErrors": true,
        "uploadOnSave": true // add to README
    }
}

Recently added minor improvements that allows to setup file patterns for auto-upload.

Updated config example:

{
    "/frontend/www": {
        "url": "https://webdav.example.com/"
    },
    "/another-frontend/www": {
        "url": "https://webdav2.example.com/",
        "ignoreSSLErrors": true,
        "uploadOnSave": {
            "enabled": true,
            "pattern": [
                ".gmi$"
            ]
        }
    }
}
