 # Environments
 
-## What is an environment?
+An Umbraco Cloud environment is defined as a _workspace_ and is at the same time a Git repository. When you have more than one environment on your project, these environments will act as branches of the main repository.
+
+Umbraco Cloud uses a deployment model that relies on Git and other core technology. This gives you the option to move both content and structure files from one environment to another. Learn more in the [Deployment section](../deployment/README.md).
+
+You can have multiple environments on your Umbraco Cloud project and there are two types of environments available. These are **Mainline Environments** and **Flexible Environments**.
+
+The image below shows a Cloud setup including 2 mainline environments and 1 flexible environment connected to the left-most mainline environment.

+## Mainline Environments
 
-When you have multiple environments in your Umbraco Cloud project:
+A mainline environment serves as the root deployment pipeline, responsible for managing code and content flow. Each mainline environment is a part of the [left-to-right deployment workflow](../deployment/README.md).
 
-*   The _Development_ environment is the first environment in the workflow.
+The **left-most mainline environment** is where you can connect to your local machine using Git. This environment is often called the Development environment.
 
-    This is the environment you are going to work with when building the structure of your website. This is also the environment you clone down when you want to work on your project locally.
+The **right-most mainline environment** is your live website, often called the Live or Production environment.
 
-    The Development environment is included in the Standard and Professional plans on Umbraco Cloud. In the Starter plan, you have the option to add the Development environment.
-*   The environment next in line in the workflow is the _Staging_ environment.
+Each mainline environment can have one or more flexible environments branching off from it.
 
-    This environment enables you to give your team members different workspaces - the developers can work with code in the Development environment while content editors can work with content in the Staging environment. All of this without affecting the actual public site.
+## Flexible Environments
 
-    The Staging environment is included in the Professional plan. In the Standard plan, you have the option to add the Staging environment.
+A flexible environment is an environment that branches off a mainline environment. It is positioned vertically from the mainline deployment flow.
 
-{% hint style="info" %}
-Both the Development and the Staging environments are protected with **basic authentication**. This means that you must log in to see the frontend of these environments.
-{% endhint %}
+Changes made on a flexible environment can only be pushed to the next designated Mainline Environment in the pipeline.
 
-*   The final environment is the _Live_ environment.
+Technically, the flexible environment connected only to its mainline environment using a Git remote. This ensures that changes follow a structured path while still allowing flexibility in development workflows.
 
-    This is your live site - the site that's visible to the public. When you are in trial mode the Live environment will be protected by basic authentication - this will be removed as soon as you set up a subscription for the project.
+Learn more about how this works in the [Flexible Environments](flexible-environments.md) article.
 
-    The Live environment is included in the Standard and Professional plans on Umbraco Cloud.

 ## Site and Git Repository
 
 Each environment on Umbraco Cloud has both a Git repository and a folder with your actual live site. The Git repository is what you clone down when you work with the project locally, and it's where your changes are pushed to.
 
-The live site (`/site/wwwroot/`) contains the files used to show your website to the world. When you push changes from your local machine, they are pushed to the Git repository (`/site/repository/`), and when this finishes successfully the changes are copied into the live site.

-All the team members you add through the Umbraco Cloud Portal will also be added as backoffice users in your environments. As with any other Umbraco CMS installation, you can also add users directly in the backoffice of your Umbraco Cloud environments. If you do this, the user will not have the option to deploy changes between the environments.
