+## Docker
+
+With Docker images, using the `awslogs` log driver will send your container logs to CloudWatch Logs. All you have to do is write to STDOUT and your EMF logs will be processed.

+## ECS and Fargate
+
+With ECS and Fargate, you can use the `awslogs` log driver to have your logs sent to CloudWatch Logs on your behalf. After configuring your task to use the `awslogs` log driver, you may write your EMF logs to STDOUT and they will be processed.

 For running on Fargate, s3 file option is not supported for Fluent-bit config. Hence, we need to build the fluent-bit custom config image and then use its reference in our Firelens container definition.
