 ## AWS Lambda Integration
 From branch: [`lambda`](https://github.com/awslabs/eb-java-scorekeep/tree/lambda)
 
-In the [`UserFactory`](https://github.com/awslabs/eb-java-scorekeep/tree/xray/src/main/java/scorekeep/UserFactory.java) class, Scorekeep calls a Node.js AWS Lambda function to generate random usernames.  If the call to Lambda fails, Scorekeep falls back on a public API to generate names. 
-
-Run the script in the `_lambda` folder to create the AWS Lambda function that Scorekeep calls to generate random names:
-
-    eb-java-scorekeep/_lambda$ ./create-random-name.sh
-
-The script uses a CloudFormation template and the AWS CLI to create the function and its execution role:
-- `_lambda/random-name.yml`       - Template that defines the role and function
-- `_lambda/create-random-name.sh` - Script to create the role and function
-- `_lambda/delete-random-name.sh` - Script to delete the role and function
-
-If you don't have the AWS CLI, [install it](http://docs.aws.amazon.com/cli/latest/userguide/installing.html) or use the CloudFormation console to create a stack with the template.
-
-Next, add Lambda permission to your instance profile ([aws-elasticbeanstalk-ec2-role](https://console.aws.amazon.com/iam/home#/roles/aws-elasticbeanstalk-ec2-role)) to let the environment update the Lambda function:
-- AWSLambdaFullAccess
-
-Note: In the `lambda` branch, Scorekeep creates the Lambda function with a configuration file. In this branch, you create the function independently with the same template that creates the role. This lets the `xray` branch work even if the Lambda function and role have not been created, whereas in the `lambda` branch, the deployment fails if you haven't created the required role.
-
-Finally, redeploy this branch to your environment. During deployment, the [update script in `lambda-function.config`](https://github.com/awslabs/eb-java-scorekeep/blob/xray/.ebextensions/lambda-function.config#L31) builds the function and uploads the source code to Lambda.
+In the [`UserFactory`](https://github.com/awslabs/eb-java-scorekeep/tree/xray/src/main/java/scorekeep/UserFactory.java) class, Scorekeep calls a Node.js AWS Lambda function to generate random usernames.
 
 Create a new user in the web app and refresh your service map to see the two Lambda nodes.
