+description: Reference information for evaluator configuration file.
+template: howto-guide-template

+
+In some cases, the evaluator's rules may cause false positive errors. Then you can configure the evaluator to ignore some errors.
+
+1. To configure the evaluator to ignore errors, add `tooling.yml` to the project's root directory.
+
+```yaml
+
+evaluator:
+  # evaluator options
+  ...
+
+```
+
+2. In the `ignoreErrors` section, add the errors to ignore using regular expressions.
+    You can specify errors to ignore globally or per specific checker.
+
+**tooling.yml**
+```yaml
+
+evaluator:
+    ignoreErrors:
+        # global error ignore regexp
+        - '#SprykerSdkTest\\InvalidProject\\MultidimensionalArray\\Application1\\ApplicationDependencyProvider#'
+        # error ignore regexp for a defined checker
+        - messages:
+              - '#deploy.*\.yml#'
+              - '#php\.7\.4#'
+          checker: PHP_VERSION_CHECKER
+```
+
+The error message matching the regular expressions should now be ignored.
