+# Included File
+
+This file is used to demonstrate **path filters** in GitHub Actions workflows.
+
+Modifying this file will trigger workflows that include `filters/included-file.md` in their path filter, unlike `excluded-file.txt` which is ignored.
+
+## Example Usage
+
+```yaml
+on:
+  push:
+    paths:
+      - 'filters/**.md'
+```
+
+## How Path Filters Work
+
+GitHub Actions supports two path filter keys:
+
+- **`paths`** — triggers the workflow when a matching file is changed.
+- **`paths-ignore`** — skips the workflow when only matching files are changed.
+
+You can also use negation patterns to fine-tune behavior:
+
+```yaml
+on:
+  push:
+    paths:
+      - '**.md'
+      - '!**/excluded-file.txt'
+```
+
+## Notes
+
+- Glob patterns follow the same syntax as `.gitignore`.
+- At least one changed file must match for the workflow to trigger.
+- `paths` and `paths-ignore` cannot be used together in the same event trigger.
