 Maven and Gradle are both build tools, which read metadata from files which guide how the code within a module should be built. Maven and Gradle use different formats for these build files. Artifacts are created on disk and can later be built, tested and deployed to a Maven repository and used in the Galasa Ecosystem. Generated artifacts can be embellished and refactored to form the basis of future Galasa tests.
 
 
-The `galasactl project create` command uses the `--maven` and `--gradle` parameters to allow you to decide which type of build system to use when creating the example project. By default, the `galasactl project create` command generates a project which includes a Maven build mechanism. You can also pass the `--maven` flag explicitly to tell the tool to generate Maven build artifacts (pom.xml files). 
+The `galasactl project create` command uses the `--maven` and `--gradle` parameters to allow you to decide which type of build system to use when you create a project. You must specify either the `--maven` flag or the `--gradle` flag when you run the `galasactl project create` command. You can specify both flags to tell the tool to generate Maven build artifacts (pom.xml files) and Gradle files.
 
 The example provided in this topic creates a project containing both Maven and Gradle build infrastructure files by specifying the `--maven` and `--gradle` parameters in the command.

When you specify the location of the OBR to Galasa, the OBR tells Galasa where the tests are stored. You can create an OBR from scratch, or you can create projects and add them into an existing OBR.
