## Add an AppSpec File

* **Note**\
  Deployments to Windows Server instances do not support the `runas` element. If you are deploying to Windows Server instances, do not include it in your AppSpec file.

## Choose a repository type

* **Note**\
  An AWS Lambda deployment works with an Amazon S3 repository only.

## Push a revision

* **Note**\
  CodeDeploy can also be used to deploy revisions that have been pushed to GitHub. For more information, see your GitHub documentation.
* **Note**\
  The `push` command bundles application artifacts and an AppSpec file into a revision. The file format of this revision is a compressed ZIP file. The command cannot be used with an AWS Lambda or an Amazon ECS deployment because each expects a revision that is a JSON-formatted or YAML-formatted AppSpec file.

## View application revision details

* **Note**\
  References to GitHub apply to deployments to EC2/On-Premises deployments only. Revisions for AWS Lambda deployments do not work with GitHub.

## Register an application revision

* **Note**\
  AWS Lambda deployments do not work with GitHub.
