+### Importing files
+
+This library has support for importing files as Symfony’s Dependency Injection component does.
+In the below example a YAML file imports three files:
+
+```yaml
+---
+imports:
+  - config-imported.yml
+  - config-imported.toml
+  - config-imported.json
+```
+
+Similar example using JSON:
+
+```json
+{
+  "imports": [
+    "config.json"
+  ]
+}
+```
+
+Example using TOML:
+
+```
+imports = [
+    "config.toml"
+]
+```
