-In the domain of software delivery, managing configurations for microservices can become complex, especially when configurations require adjustments across various stages of the software lifecycle. MicroProfile Config's configuration profile feature, also known as the https://download.eclipse.org/microprofile/microprofile-config-3.0/microprofile-config-spec-3.0.html#configprofile[Config Profile^], is a direct solution to this challenge. It simplifies the management of microservice configurations across diverse environments - from development to production and throughout the CI/CD pipeline. By tailoring configuration properties to each environment, the deployment process becomes more seamless, allowing developers to concentrate on perfecting their application's delivery.

-You'll learn how to provide environment-specific configurations by using the MicroProfile Config's configuration profile feature. You'll create configuration profiles at both the individual property level and the higher-level configuration sources.
+You'll learn how to provide environment-specific configurations by using the MicroProfile Config's configuration profile feature. You'll create configuration profiles using individual configuration properties and default configuration source working working with MicroProfile Config API.
 
 This guide builds on the basics of the https://openliberty.io/guides/microprofile-config-intro.html[Separating configuration from code in microservices^] guide and the https://openliberty.io/guides/microprofile-config.html[Configuring microservices^] guide. If you are not familiar with externalizing the configuration of microservices, it will be helpful to read the https://openliberty.io/docs/latest/external-configuration.html[External configuration of microservices^] document and complete those guides before proceeding.
 
-The application that you will work with is a `query` service, which fetches information about the running JVM from a `system` microservice. Given the variances in accessing parameters between development, testing, and production environments, you'll use the configuration profile feature to provide optimal configurations for these interactions.
