+
+This AWS Solutions Construct implements an AWS EventBridge rule and an AWS Lambda function.
+
+Here is a minimal deployable pattern definition in Typescript:
+
+``` javascript
+const { EventbridgeToLambdaProps, EventbridgeToLambda } from '@aws-solutions-constructs/aws-eventbridge-lambda';
+
+const props: EventbridgeToLambdaProps = {
+    lambdaFunctionProps: {
+        code: lambda.Code.fromAsset(`${__dirname}/lambda`),
+        runtime: lambda.Runtime.NODEJS_12_X,
+        handler: 'index.handler'
+    },
+    eventRuleProps: {
+      schedule: events.Schedule.rate(Duration.minutes(5))
+    }
+};
+
+new EventbridgeToLambda(this, 'test-eventbridge-lambda', props);
+```
+
+## Initializer
+
+``` text
+new EventbridgeToLambda(scope: Construct, id: string, props: EventbridgeToLambdaProps);
+```
+
+_Parameters_
+
+* scope [`Construct`](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_core.Construct.html)
+* id `string`
+* props [`EventbridgeToLambdaProps`](#pattern-construct-props)
+
+## Pattern Construct Props
+
+| **Name**     | **Type**        | **Description** |
+|:-------------|:----------------|-----------------|
+|existingLambdaObj?|[`lambda.Function`](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-lambda.Function.html)|Existing instance of Lambda Function object, providing both this and `lambdaFunctionProps` will cause an error.|
+|lambdaFunctionProps?|[`lambda.FunctionProps`](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-lambda.FunctionProps.html)|User provided props to override the default props for the Lambda function.|
+|eventRuleProps|[`events.RuleProps`](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-events.RuleProps.html)|User provided eventRuleProps to override the defaults|
+
+## Pattern Properties
+
+| **Name**     | **Type**        | **Description** |
+|:-------------|:----------------|-----------------|
+|eventsRule|[`events.Rule`](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-events.Rule.html)|Returns an instance of events.Rule created by the construct|
+|lambdaFunction|[`lambda.Function`](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-lambda.Function.html)|Returns an instance of lambda.Function created by the construct|
+
+## Default settings
+
+Out of the box implementation of the Construct without any override will set the following defaults:
+
+### Amazon EventBridge Rule
+* Grant least privilege permissions to EventBridge rule to trigger the Lambda Function
+
+### AWS Lambda Function
+* Configure limited privilege access IAM role for Lambda function
+* Enable reusing connections with Keep-Alive for NodeJs Lambda function
+* Enable X-Ray Tracing
+* Set Environment Variables
+  * AWS_NODEJS_CONNECTION_REUSE_ENABLED (for Node 10.x and higher functions)
