AI Language Review

The document "Getting Started with Observability Kit" is generally well-written and clear. However, there are a few areas that could benefit from improvements:

1. The section "TODO ask from the dev team what to do with this section" contains a placeholder that suggests missing information. Ensure that this section is clarified before publication if the information is necessary.

2. The use of role="since:com.vaadin:[email protected]" appears unsupported or unclear without additional context or explanation in the document. If it's meant to convey version-specific information, it should be properly integrated or omitted if unnecessary.

3. In the "Run the Application" section, the phrase "You're now ready to run your application" can be more engaging by focusing on the action: "Run your application by..."

Overall, ensure placeholders are resolved, and enhance engagement by occasionally using direct action statements.
