+## Summary
+
+[Amazon Elastic Container Service (ECS)](https://aws.amazon.com/ecs/) is a highly scalable, high-performance container orchestration service that supports Docker containers and allows you to easily run and scale containerized applications on AWS.
+ECS is a widely used service in AWS.
+But there is no Chaos Fault for ECS in Litmus ChaosHub.
+So I want to add a new Chaos Fault for ECS.
+Adding 'ecs task stop' Chaos Fault to Litmus ChaosHub can help create a more resilient system.
+
+## Motivation
+
+Litmus ChaosHub has plenty of Chaos Faults.
+But there is no Chaos Fault for Amazon ECS.
+ECS is a widely used service in AWS.
+So I want to add a new Chaos Fault for ECS.
+Adding 'ecs task stop' Chaos Fault to Litmus ChaosHub can help create a more resilient system.
+
+### Goals
+
+- Adding an 'ecs task stop' Chaos Fault to [Litmus ChaosHub](https://hub.litmuschaos.io/)
+- Fixing [litmus-go](https://github.com/litmuschaos/litmus-go) and [chaos-charts](https://github.com/litmuschaos/chaos-charts) codes
+
+### Non-Goals
+
+- Fixing Litmus codes except for [litmus-go](https://github.com/litmuschaos/litmus-go) and [chaos-charts](https://github.com/litmuschaos/chaos-charts) is a non-goal
+
+## Proposal
+
+### Use Cases
+
+#### Use case 1
+
+In Chaos Studio, Users can select 'ecs task stop' Chaos Fault as part of the Chaos Experiment.
+They can compose it with other Chaos Faults.
+
+### Implementation Details
+
+Here's a Chaos Fault Scenario.
+

+
+#### Phase 1 - Add scenario to the litmus-go repository
+
+I will use `litmuschaos/go-runner` image.
+So I am going to add a new case in the litmus-go repository.
+
+#### Phase 2 - Add a new Chaos Fault to the Litmus ChaosHub
+
+After Phase 1 PR gets merged, I will raise a PR that adds an 'ecs task stop' Chaos Fault to the `chaos-charts` repository.
+When all is done, the user can easily assault the ECS service.
+
+## Risks and Mitigations
+
+We need to grant proper RBAC permissions to the runner container.
+Granting override permissions may affect other systems.
