+By default, the following file patterns are considered important and will trigger a release:
+
+| Pattern | Description |
+| :------ | :---------- |
+| `^src/` | Module source code |
+| `^README\.md$` | Module documentation |
+
+These patterns are regular expressions matched against the file paths changed in a pull request.
+
+#### Customizing important file patterns
+
+You can override the default patterns using the `Publish.Module.ImportantFilesPatterns` setting in your
+`PSModule.yml` file. The value is a comma-separated list of regular expression patterns:
+
+```yaml
+Publish:
+  Module:
+    ImportantFilesPatterns: '^src/, ^README\.md$'
+```
+
+For example, to also trigger releases when example scripts or a changelog are modified:
+
+```yaml
+Publish:
+  Module:
+    ImportantFilesPatterns: '^src/, ^README\.md$, ^examples/, ^CHANGELOG\.md$'
+```

+Changes to files that do not match any of the important file patterns will not trigger a release.

 - `.github/linters/*` - Linter configuration files
