+## Environment types
+
+All environments in Unleash have a **type**. When you create a new environment, you must also assign it a type.
+
+The built-in environment types are:
+- Development
+- Test
+- Pre-production
+- Production
+
+The **production** environment type is special: Unleash will show additional confirmation prompts when you change something that could impact users in environments of this type. The built-in "production" environment is a production-type environment.
+
+The other environment types do not currently have any functionality associated with them. This may change in the future.

Environments exist on a global level, so they are available to all projects within Unleash. However, every [project](./projects.md) might not need to use every environment. That's why you can also choose which of the global environments should be available within a project.
