+## VPC Flow Log
+
+VPC Flow Log allows to capture IP traffic for a specific network interface (ENI), subnet, or entire VPC. This module supports enabling or disabling VPC Flow Logs for entire VPC. If you need to have VPC Flow Logs for subnet or ENI, you have to manage it outside of this module with [aws_flow_log resource](https://www.terraform.io/docs/providers/aws/r/flow_log.html).

 ## Conditional creation
 
 Sometimes you need to have a way to create VPC resources conditionally but Terraform does not allow to use `count` inside `module` block, so the solution is to specify argument `create_vpc`.

+# VPC with enabled VPC flow log to S3 and CloudWatch logs
+
+Configuration in this directory creates a set of VPC resources with VPC Flow Logs enabled in different configurations:
+
+1. `cloud-watch-logs.tf` - Push logs to a new AWS CloudWatch Log group.
+1. `cloud-watch-logs.tf` - Push logs to an existing AWS CloudWatch Log group using existing IAM role (created outside of this module).
+1. `s3.tf` - Push logs to an existing S3 bucket (created outside of this module).
+
+## Usage
+
+To run this example you need to execute:
+
+```bash
+$ terraform init
+$ terraform plan
+$ terraform apply
+```
+
+Note that this example may create resources which can cost money (AWS Elastic IP, for example). Run `terraform destroy` when you don't need these resources.
