+# Contributing
+
+Thanks for considering contributing and making our planet easier to explore!
+
+We're excited you would like to contribute to Cumulus! Whether you're finding bugs, adding new features, fixing anything broken, or improving documentation, get started by submitting an issue or pull request!
+
+## Submitting an Issue
+
+If you have any questions or ideas, or notice any problems or bugs, first [search open issues](https://github.com/cumulus-nasa/cumulus-ecs-task/issues) to see if the issue has already been submitted. We may already be working on the issue. If you think your issue is new, you're welcome to [create a new issue](https://github.com/cumulus-nasa/cumulus-ecs-task/issues/new).
+
+## Pull Requests
+
+If you want to submit your own contributions, follow these steps:
+
+* Fork the Cumulus repo
+* Create a new branch from the branch you'd like to contribute to
+* If an issue does't already exist, submit one (see above)
+* [Create a pull request](https://help.github.com/articles/creating-a-pull-request/) from your fork into the target branch of the cumulus-nasa/cumulus repo
+* Be sure to [mention the corresponding issue number](https://help.github.com/articles/closing-issues-using-keywords/) in the PR description, i.e. "Fixes Issue #10"
+* Upon submission of a pull request, the Cumulus development team will review the code
+* The request will then either be merged, declined, or an adjustment to the code will be requested
+
+## Guidelines
+
+We ask that you follow these guidelines with your contributions:
+
+### Tests
+
+All of the automated tests for this project need to pass before your submission will be accepted. You can run `npm test` in the command line after making changes to verify that the tests pass. If you add new functionality, please consider adding tests for that functionality as well.
+
+### Commits
+
+* Make small commits that show the individual changes you are making
+* Write descriptive commit messages that explain your changes
+
+Example of a good commit message;
+
+```
+Improve contributing guidelines. Fixes #10
+
+Improve contributing docs and consolidate them in the standard location https://help.github.com/articles/setting-guidelines-for-repository-contributors/
+```
+
+### For more information on Cumulus governance, see the [Cumulus Code Contribution Guidelines](https://docs.google.com/document/d/14J_DS6nyQ32BpeVjdR-YKfzHAzFB299tKghPGshXUTU/edit) and [the Cumulus Wiki](https://wiki.earthdata.nasa.gov/display/CUMULUS/Cumulus).

+# cumulus-ecs-task
+
+Use this Docker image to run a Node.js Lambda function in AWS [ECS](https://aws.amazon.com/ecs/).
+
+## Environment variables expected
+
+`AWS_DEFAULT_REGION` – defaults to `us-east-1`
+
+## Useful Commands
+
+To build:
+
+```
+npm run docker:build
+```
+
+To run locally:
+
+```
+./bin/service.js --activityArn <activity-arn> --lambdaArn <lambda-arn>
+```
+
+To run in Docker locally:
+
+```
+docker run -e AWS_ACCESS_KEY_ID='<aws-access-key>' \
+  -e AWS_SECRET_ACCESS_KEY='<aws-secret-key>' \
+  cumuluss/cumulus-ecs-task \
+  --activityArn <activity-arn> \
+  --lambdaArn <lambda-arn> \
+```
+
+To deploy to the AWS repo:
+
+```
+export AWS_ACCOUNT_ID=<your-account-id>
+docker tag cumulus-ecs-task:latest $AWS_ACCOUNT_ID.dkr.ecr.us-east-1.amazonaws.com/cumulus-ecs-task:latest
+docker push $AWS_ACCOUNT_ID.dkr.ecr.us-east-1.amazonaws.com/cumulus-ecs-task:latest
+
+```
+
+To clean up local deployments after repeated builds:
+
+```
+npm run docker:clean
+```

+## About
 
-`AWS_DEFAULT_REGION` – defaults to `us-east-1`
+cumulus-ecs-task is a Docker image that can run Lambda functions as ECS services.
 
-## Useful Commands
+When included in a Cumulus workflow and deployed to AWS, it will download a specified Lambda function, and act as an activity in a Step Functions workflow.
 
-To build:
+## Compatibility
+
+TODO: update when new cumulus release goes out with cumulus-message-adapter-js version bump
+
+This only works with Node.js Lmabda functions.
+
+## Usage
+
+Like other Cumulus libraries, cumulus-ecs-task is designed to be deployed to AWS using [kes](https://github.com/developmentseed/kes) to manage Cloudformation config. This documentation assumes you're working with a Cumulus deployment and that you have files and directory stucture similar to what's found in the [cumulus template repository](https://github.com/cumulus-nasa/template-deploy).
+
+Most importantly, we'll need to edit these files:
+
+- lambdas.yml
+- workflows.yml
+- app/config.yml
+- iam/cloudformation.template.yml
+
+### Options
+
+This library has two options:
+
+- `activityArn` **required**
+  - The arn of the activity in a step functions workflow. Used to receive messages for that activity and send success/failure responses.
+- `lambdaArn` **required**
+  - The arn of the lambda function you want to run in ECS.
+
+### lambdas.yml config
+
+There's no config in lambdas.yml that is special to ecs-cumulus-task, just make sure to add the lambda that will be run in ECS. We won't use that lambda directly in workflows.yml, but we will reference the arn of the lambda in workflows.yml.
+
+### workflows.yml config
+
+An example state of a workflow in workflows.yml:
 
 ```
-npm run docker:build
+EcsTaskHelloWorld:
+  CumulusConfig:
+    buckets: '{$.meta.buckets}'
+    provider: '{$.meta.provider}'
+    collection: '{$.meta.collection}'
+  Type: Task
+  Resource: ${EcsTaskHelloWorldActivity}
+  Next: < ... next state in the workflow ... >
 ```
 
+The important line is `Resource: ${EcsTaskHelloWorldActivity}`.
+
+We'll define that activity in the app/config.yml file.
+
+### ECS config
+
+This library requires additional configuration to be added to the app/config.yml file under the `ecs` block, as well as a list of activity names under `activities`.
+
+Here's an example:
+
+```yml
+yourdeployment:
+  ecs:
+    instanceType: t2.small
+    desiredInstances: 1
+    availabilityZone: us-east-1a
+    imageId: ami-a7a242da
+    publicIp: true
+    docker: 
+      username: cumulususer
+    services:
+      EcsTaskHelloWorld:
+        image: cumuluss/cumulus-ecs-task:0.0.1
+        cpu: 800
+        memory: 1500
+        count: 0
+        envs:
+          AWS_DEFAULT_REGION:
+            function: Fn::Sub
+            value: '${AWS::Region}'
+        commands:
+          - cumulus-ecs-task
+          - '--activityArn'
+          - function: Ref
+            value: EcsTaskHelloWorldActivity
+          - '--lambdaArn'
+          - function: Ref
+            value: EcsTaskHelloWorldLambdaFunction
+
+  activities:
+    - name: EcsTaskHelloWorld
+```
+
+Under `activities` we define the activity name `EcsTaskHelloWorld`, which can then be referenced to in the `ecs` section and in workflows.yml as `EcsTaskHelloWorldActivity`.
+
+We can give our service the same name as the activity. Be sure to double-check the options like `cpu`, `memory`, and others to be sure they'll work with your use case.
+
+Note that under the the `commands` section we're referencing the `EcsTaskHelloWorldActivity` as the `activityArn` and the `EcsTaskHelloWorldLambdaFunction` as the `lambdaArn`.
+
+
+### IAM permissions
+
+The `EcsRole` will need to include permissions to send requests to the step functions API.
+
+The following should be included in the `Statement` of the `EcsRole` policy:
+
+```yml
+# Allow state machine interactions
+- Effect: Allow
+  Action:
+  - states:SendTaskFailure
+  - states:SendTaskSuccess
+  - states:SendTaskHeartbeat
+  - states:GetActivityTask
+  Resource: arn:aws:states:*:*:*
+```

+### To test a workflow while developing locally
+
+You can execute workflows on AWS that test the version of cumulus-ecs-task that you're developing on locally.
+
+First, make sure that the ECS cluster for your deployment has zero tasks running that might respond to a workflow's requests.
+
+That way only your local version will respond to your workflow.
+
+Next, start ecs-cumulus-task locally.
+
+Either with node:
+
+```
+npm start -- --activityArn <your-activity-arn> --lambdaArn <your-lambda-arn>
+```
+
+Or with docker:
