# JRuby


You can add support for the CodeGuru Profiler agent into your JRuby application by adding the following lines into your startup or `main` function. 

```
Java::SoftwareAmazonCodeguruprofilerjavaagent::Profiler
    .builder
    .profiling_group_name("MyProfilingGroup")
    .aws_credentials_provider(myAwsCredentialsProvider) # optional
    .build
    .start
...
```

You need to [add a dependency](enabling-the-agent-with-code.md) to the agent .jar file.
