-Vitest provides built-in support for monorepos through a workspace configuration file. You can create a workspace to define your project's setups.
+Vitest provides a way to define multiple project configurations within a single Vitest process. This feature is particularly useful for monorepo setups but can also be used to run tests with different configurations, such as `resolve.alias`, `plugins`, or `test.browser` and more.
 
 ## Defining a Workspace
