+This AWS Solutions Construct implements an AWS Fargate service that can write/read to an Amazon S3 Bucket
+
+Here is a minimal deployable pattern definition in Typescript:
+
+``` typescript
+import { FargateToS3, FargateToS3Props } from '@aws-solutions-constructs/aws-fargate-s3';
+
+const props: FargateToS3Props = {
+  publicApi: true,
+  ecrRepositoryArn: "arn of a repo in ECR in your account",
+});
+
+new FargateToS3(stack, 'test-construct', props);
+```
+
+## Initializer
+
+``` text
+new FargateToS3(scope: Construct, id: string, props: FargateToS3Props);
+```
+
+_Parameters_
+
+* scope [`Construct`](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_core.Construct.html)
+* id `string`
+* props [`FargateToS3Props`](#pattern-construct-props)
+
+## Pattern Construct Props
+
+| **Name**     | **Type**        | **Description** |
+|:-------------|:----------------|-----------------|
+| publicApi | boolean | Whether the construct is deploying a private or public API. This has implications for the VPC and ALB. |
+| vpcProps? | [ec2.VpcProps](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-ec2.VpcProps.html) | Optional custom properties for a VPC the construct will create. This VPC will be used by the new ALB and any Private Hosted Zone the construct creates (that's why loadBalancerProps and privateHostedZoneProps can't include a VPC). Providing both this and existingVpc is an error. |
+| existingVpc? | [ec2.IVpc](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-ec2.IVpc.html) | An existing VPC in which to deploy the construct. Providing both this and vpcProps is an error. If the client provides an existing load balancer and/or existing Private Hosted Zone, those constructs must exist in this VPC. |
+| clusterProps? | [ecs.ClusterProps](https://docs.aws.amazon.com/cdk/api/v1/docs/@aws-cdk_aws-ecs.ClusterProps.html) | Optional properties to create a new ECS cluster. To provide an existing cluster, use the cluster attribute of fargateServiceProps. |
+| ecrRepositoryArn? | string | The arn of an ECR Repository containing the image to use to generate the containers. Either this or the image property of containerDefinitionProps must be provided. format: arn:aws:ecr:*region*:*account number*:repository/*Repository Name* |
+| ecrImageVersion? | string | The version of the image to use from the repository. Defaults to 'Latest' |
+| containerDefinitionProps? | [ecs.ContainerDefinitionProps \| any](https://docs.aws.amazon.com/cdk/api/v1/docs/@aws-cdk_aws-ecs.ContainerDefinitionProps.html) | Optional props to define the container created for the Fargate Service (defaults found in fargate-defaults.ts) |
+| fargateTaskDefinitionProps? | [ecs.FargateTaskDefinitionProps \| any](https://docs.aws.amazon.com/cdk/api/v1/docs/@aws-cdk_aws-ecs.FargateTaskDefinitionProps.html) | Optional props to define the Fargate Task Definition for this construct  (defaults found in fargate-defaults.ts) |
+| fargateServiceProps? | [ecs.FargateServiceProps \| any](https://docs.aws.amazon.com/cdk/api/v1/docs/@aws-cdk_aws-ecs.FargateServiceProps.html) | Optional values to override default Fargate Task definition properties (fargate-defaults.ts). The construct will default to launching the service is the most isolated subnets available (precedence: Isolated, Private and Public). Override those and other defaults here. |
+| existingFargateServiceObject? | [ecs.FargateService](https://docs.aws.amazon.com/cdk/api/v1/docs/@aws-cdk_aws-ecs.FargateService.html) | A Fargate Service already instantiated (probably by another Solutions Construct). If this is specified, then no props defining a new service can be provided, including: existingImageObject, ecrImageVersion, containerDefintionProps, fargateTaskDefinitionProps, ecrRepositoryArn, fargateServiceProps, clusterProps, existingClusterInterface |
+| existingContainerDefinitionObject? | [ecs.ContainerDefinition](https://docs.aws.amazon.com/cdk/api/v1/docs/@aws-cdk_aws-ecs.ContainerDefinition.html) | A container definition already instantiated as part of a Fargate service. This must be the container in the existingFargateServiceObject |
+|existingBucketInterface?|[`s3.IBucket`](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-s3.IBucket.html)|Existing S3 Bucket interface. Providing this property and `bucketProps` results in an error.|
+|bucketProps?|[`s3.BucketProps`](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-s3.BucketProps.html)|Optional user provided props to override the default props for the S3 Bucket.|
+|loggingBucketProps?|[`s3.BucketProps`](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-s3.BucketProps.html)|Optional user provided props to override the default props for the S3 Logging Bucket.|
+|logS3AccessLogs?| boolean|Whether to turn on Access Logging for the S3 bucket. Creates an S3 bucket with associated storage costs for the logs. Enabling Access Logging is a best practice. default - true|
+|bucketPermissions?|`string[]`|Optional bucket permissions to grant to the Lambda function. One or more of the following may be specified: `Delete`, `Put`, `Read`, `ReadWrite`, `Write`.|
+|bucketArnEnvironmentVariableName?|string|Optional Name for the S3 bucket arn environment variable set for the container.|
+|bucketEnvironmentVariableName?|string|Optional Name for the S3 bucket name environment variable set for the container.|
+
+## Pattern Properties
+
+| **Name**     | **Type**        | **Description** |
+|:-------------|:----------------|-----------------|
+| vpc | [ec2.IVpc](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-ec2.IVpc.html) | The VPC used by the construct (whether created by the construct or providedb by the client) |
+| service | [ecs.FargateService](https://docs.aws.amazon.com/cdk/api/v1/docs/@aws-cdk_aws-ecs.FargateService.html) | The AWS Fargate service used by this construct (whether created by this construct or passed to this construct at initialization) |
+| container | [ecs.ContainerDefinition](https://docs.aws.amazon.com/cdk/api/v1/docs/@aws-cdk_aws-ecs.ContainerDefinition.html) | The container associated with the AWS Fargate service in the service property. |
+| s3Bucket? |[s3.IBucket](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-s3.IBucket.html)|Returns an instance of s3.Bucket created by the construct|
+| s3BucketInterface |[`s3.IBucket`](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-s3.IBucket.html)|Returns an instance of s3.IBucket created by the construct|
+| s3LoggingBucket?	| [s3.Bucket](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-s3.Bucket.html)|Returns an instance of s3.Bucket created by the construct|
+
+## Default settings
+
+Out of the box implementation of the Construct without any override will set the following defaults:
+
+### AWS Fargate Service
+* Sets up an AWS Fargate service
+  * Uses the existing service if provided
+  * Creates a new service if none provided.
+    * Service will run in isolated subnets if available, then private subnets if available and finally public subnets
+  * Adds environment variables to the container with the ARN and Name of the S3 Bucket
+  * Add permissions to the container IAM role allowing it to publish to the S3 Bucket
+
+### Amazon S3 Bucket
+* Sets up an Amazon S3 Bucket
+  * Uses an existing bucket if one is provided, otherwise creates a new one
+* Adds an Interface Endpoint to the VPC for S3 (the service by default runs in Isolated or Private subnets)
