 ### Custom IAM and STS Endpoints

+Local Endpoints can be configured to use custom IAM and STS endpoints. Simply define the `IAM_ENDPOINT` and `STS_ENDPOINT` environment variables in the Local Endpoints container.
 
 This may be useful in scenarios where your application container is configured to obtain credentials from ECS (see [Vend Credentials to Containers](features.md#vend-credentials-to-containers)), but you do not want to provide Local Endpoints with AWS credentials. Providing an IAM and STS simulator and configuring the Local Endpoints container with custom IAM and STS endpoints enables testing without an AWS account.

+# Continuous delivery pipelines
+
+This package uses the [AWS Cloud Development Kit (AWS)](https://github.com/awslabs/aws-cdk) to model AWS CodePipeline pipelines and to provision them with AWS CloudFormation.
+
+* pipeline.ts: Builds and publishes the base Docker image for amazon/amazon-ecs-local-container-endpoints.
+
+This creates as CodePipeline pipeline which consists of a souce stage that uses
+a GitHub webhook, and build stages that uses AWS CodeBuild to build, publish
+and verify Docker images for both amd64 and arm64 architectures to DockerHub.
+
+## GitHub Access Token
+The official pipeilne uses a team account (ecs-local-container-endpoints+release@amazon.com).
+
+Create a GitHub [personal access token](https://github.com/settings/tokens) with access to your fork of the repo, including "admin:repo_hook" and "repo" permissions.  Then store the token in Secrets Manager:
+
+```
+aws secretsmanager create-secret --region us-west-2 --name EcsDevXGitHubToken --secret-string <my-github-personal-access-token>
+```
+
+## Deploy
+
+To deploy this pipeline, install the AWS CDK CLI: `npm i -g aws-cdk`
+
+Install and build everything: `npm install && npm run build`
+
+Then deploy the pipeline stacks:
+
+```
+cdk deploy --app 'node pipeline.js'
+
+```
+
+See the pipelines in the CodePipeline console.
