 ## Check the source code [#source-code]
 
 This integration is open source software. This means you can [browse its source code](https://github.com/newrelic/nri-ecs) and send improvements, or create your own fork and build it.

+
+## Monitor with APM language agents [#monitor-with-apm]
+
+You can also set up the APM language agents to run in your ECS Fargate environment. For more details, please see the [APM Agent in ECS Setup Guide](/docs/infrastructure/elastic-container-service-integration/monitor-ecs-with-apm-agents).

+
+You can install New Relic application monitoring (APM) agents on your [Amazon ECS](https://docs.aws.amazon.com/ecs/index.html) environment. When you instrument your environment with Docker, you can collect and send APM data and metrics to the New Relic platform.
+
+## Install the agent into your Docker container [#install-the-agent]
+
+To add the agent into your Docker container, follow the installation steps specific to the language agent you are using:
+
+     * [Java](https://docs.newrelic.com/docs/apm/agents/java-agent/additional-installation/install-new-relic-java-agent-docker/)
+     * [.NET](https://docs.newrelic.com/install/dotnet/?deployment=linux&docker=yesDocker)
+     * [Node.js](https://docs.newrelic.com/docs/apm/agents/nodejs-agent/installation-configuration/install-nodejs-agent-docker/)
+     * [Python](https://docs.newrelic.com/install/python/)
+
+
+## Set up the agent in your ECS task definition [#agent-task-def]
+
+In order to get the agent running in your ECS environment, you need to modify your [task defintion file](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/task_definitions.html). This file lets you specify parameters you want your app to run with. For agent set-up, you need to define the following environment variables:

+## Set up the infra agent as a sidecar [#infra-agent-side-car]
+
+You can set up the infrastructure agent as a [sidecar container](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/fargate-security-considerations.html) to your APM agents, giving you more visibility into your environment. When you set up a sidecar to your APM agent, you establish relationship between application and infrastructure monitoring so the data is correlated. This surfaces data to various New Relic mapping features, like [service maps](/docs/new-relic-solutions/new-relic-one/ui-data/service-maps/service-maps).

+Once you've modified your task file, trigger some data in your environment, wait a few minutes, then [look for your data in the UI](/docs/ecs-integration-understand-use-data).
+
+## What's next? [#next-steps]
+
+After you've setup your agents:
+
+* We recommend installing our [ECS cloud integration](/docs/integrations/amazon-integrations/aws-integrations-list/aws-ecsecr-monitoring-integration), which surfaces other ECS data, like data about clusters and services.
+* Review our doc on [alert conditions](/docs/ecs-integration-recommended-alert-conditions).
+* If you want to make additional configurations to your APM agents, check out their configuration docs:
+     * [Java](https://docs.newrelic.com/docs/apm/agents/java-agent/configuration/java-agent-configuration-config-file/)
+     * [.NET](https://docs.newrelic.com/docs/apm/agents/net-agent/configuration/net-agent-configuration/)
+     * [Node.js](https://docs.newrelic.com/docs/apm/agents/nodejs-agent/installation-configuration/nodejs-agent-configuration/)
+     * [Python](https://docs.newrelic.com/docs/apm/agents/python-agent/configuration/python-agent-configuration/)
