 The Node Red Editor is available at *http://homebridge_server_host:1956/red* , where 1956 must be changed in case you have configured another port number.
 
  
+The Node Red system does not use a settings.js file, instead some primary settings are hardcoded into the plugin. Arbitrary settings (see a settings.js file) may be added
+via the plugin's configuration. Each setting has a name, which corresponds to property names in settings.js. Each setting also has a value. These values are identical to the
+values described in settings.js. These values are javascript values and the setting value to enter is a JSON representation of the value.
+String values, must be enclosed in double-quote characters. Since object property names are represented as strings in JSON, these must also be enclosed in double-quotes.
+The use of double-quote characters should be applied in case you enter the vales using the plugin's configuration UI. In case you edit the config.json directly, all JSON double-quote
+characters have to be escaped (prepended) by a backslash ('\') character. If you enter double-quotes in the plugin's UI, you could then have a look at the config.json and you should then
+see that the double-quotes has been escaped.
