# Environments

> Manage Remote Config environments to group Game Overrides and Settings.

Unity Remote Config uses environments to group Game Overrides and Settings, and deliver specific environments to the client (Unity Runtime Instance) based on the `environmentId`. If no `environmentId` is provided in the request - the default environment, which is the environment named `production` is returned to that instance.

Use the [Unity Dashboard](http://cloud.unity.com/remote-config) to manage your Remote Config environments. Upon initialization in a new project, only the default environment is available.

## Restrictions

* A project can have a maximum of 25 environments
* Environment names must be unique
* The `development` environment name is reserved, and cannot be created by users for users of `Remote Config SDK Version` \<= `@1.1.x`
* The `production` environment name is reserved, and it is the default environment. If an environmentID is NOT specified in the request the environment `production` will be served.

## Working with environments

The [Unity Dashboard](http://cloud.unity.com/remote-config) lets you create, edit, and delete environments. This functionality is also available in the [REST APIs](./_index.md#remote-config-interfaces).

Each environment has the following main parameters.

| **Parameter**        | **Description**                                                                                                                                                                                                                                               |
| -------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Environment Name** | The readable identifier for the environment. For example, you might name an environment to match a given build of your game `com_Unity_MyGame-1_1_1`; or for a team member, to let them work independently of the settings used by others `yourNameGoesHere`. |
| **Environment Id**   | The generated UUID (universally unique identifier) for the environment. The client uses this when requesting the Rules and Settings. This parameter is required for integration.                                                                              |
| **is Default**       | This is not a user controllable flag as of 2021-07-30; the Environment Named `production` will be served as the default environment for builds that do not specify an EnvironmentID                                                                           |
