-A lab should focus on a team that's working in a feature area. This common focus allows faster changes, while limiting any negative effects to a smaller group. Changes or problems happen in the lab environment, without affecting anything else.
+A lab should be used only by a team that's working on a feature area. This focus enables faster changes but limits any negative effects to a smaller group. Changes or problems happen in the lab environment, without affecting anything else.
 
-The common focus allows for sharing area-specific resources, like tools, scripts, and Azure Resource Manager (ARM) templates. Developers can use shared resources to create virtual machines (VMs) with all the code, tools, and configuration they need. ARM templates create lab VMs and lab environments with the appropriate Azure resources. The templates create resources dynamically, or by creating base images with customizations.

 Here are some benefits of using labs in DevOps workflows:
 
-- **Focused access:** Using a lab as a component associates a specific ecosystem with limited people. Usually, a team or group working in a common area or a specific feature has a lab assigned to them.

-- **Infrastructure replication in the cloud:** A developer can quickly set up a development ecosystem that includes a developer VM with source code and tools. A developer can also create an environment that's nearly identical to the production configuration, for faster inner loop development.

 ## Use labs in CI/CD pipelines
 
 The CI/CD pipeline is a critical DevOps component. The pipeline integrates the code from a developer's pull request with existing code, and deploys the code to the production ecosystem. For DevTest Labs integration, not all resources need to be in a lab. For example, you could set up a Jenkins host outside the lab for a more persistent resource. Here are some specific examples of integrating labs into the CI/CD pipeline.
 
 ### Build
 
-The build pipeline creates a package of components to test together and hand off to release. Dynamically building infrastructure allows for greater control. Labs can be part of the build pipeline as locations for build agents and other support resources. DevTest Labs can restrict lab access, which increases security for build agents and reduces the possibility of accidental corruption.

-With the ability to have multiple environments in a lab, each build can run asynchronously. The build ID is part of the environment information that uniquely identifies the resources in a specific build.

 ### Test
 
-A CI/CD pipeline can automate creating DevTest Labs resources like VMs and environments for automated and manual testing. The pipeline uses build information artifacts or formulas to create VMs with different custom test configurations.

 ### Release
 
 The release process can use DevTest Labs for verification before the code is deployed. The process is similar to testing. Production resources shouldn't be deployed in DevTest Labs.
 
 ### Customization
 
-[Azure Pipelines](/azure/devops/pipelines/get-started/what-is-azure-pipelines), a component of Azure DevOps Services, has existing tasks to manipulate VMs and environments within specific labs. Azure Pipelines is one way to manage the CI/CD pipeline. You can integrate a lab into any system that supports calling REST APIs, executing PowerShell scripts, or using Azure CLI.

-Some CI/CD pipeline managers have existing open-source plugins that can manage Azure and DevTest Labs resources. You might need to use custom scripting to fit the needs of the pipeline. When executing a task, use a service principal with the appropriate role, usually Contributor, to access the lab.
