 ### Coverage Thresholds
 
+> [!WARNING]
+> Currently, this action does not import the vite-configuration, but parses it as string to extract the coverage-thresholds by an regexp. In other words: All thresholds need to be directly defined in the config-file given to this action through the vite-config-path input. E.g., when using workspace to extend a parent-configuration, the thresholds can not be defined in the parent-config.
+
 This action reads the coverage thresholds specified in the `coverage` property of the Vite configuration file. It then uses these thresholds to determine the status of the generated report.
 
 For instance, consider the following configuration:
