 Introducing new [Parse Server configuration][config] parameters requires the following steps:
 
 1. Add parameters definitions in [/src/Options/index.js][config-index].
-1. If a nested configuration object has been added, add the environment variable option prefix to `getENVPrefix` in [/resources/buildConfigDefinition.js](https://github.com/parse-community/parse-server/blob/master/resources/buildConfigDefinition.js).
-1. Execute `npm run definitions` to automatically create the definitions in [/src/Options/Definitions.js][config-def] and [/src/Options/docs.js][config-docs].
-1. Add parameter value validation in [/src/Config.js](https://github.com/parse-community/parse-server/blob/master/src/Config.js).
-1. Add test cases to ensure the correct parameter value validation. Parse Server throws an error at launch if an invalid value is set for any configuration parameter.
-1. Execute `npm run docs` to generate the documentation in the `/out` directory. Take a look at the documentation whether the description and formatting of the newly introduced parameters is satisfactory.
+2. If the new parameter does not have one single value but is a parameter group (an object containing multiple sub-parameters):
+   - add the environment variable prefix for the parameter group to `nestedOptionEnvPrefix` in [/resources/buildConfigDefinition.js](https://github.com/parse-community/parse-server/blob/master/resources/buildConfigDefinition.js)
+   - add the parameter group type to `nestedOptionTypes` in [/resources/buildConfigDefinition.js](https://github.com/parse-community/parse-server/blob/master/resources/buildConfigDefinition.js)
+  
+    For example, take a look at the existing Parse Server `security` parameter. It is a parameter group, because it has multiple sub-parameter such as `checkGroups`. Its interface is defined in [index.js][config-index] as `export interface SecurityOptions`. Therefore, the value to add to `nestedOptionTypes` would be `SecurityOptions`, the value to add to `nestedOptionEnvPrefix` would be `PARSE_SERVER_SECURITY_`.
