 You can also implement [`Source`](https://github.com/uchuhimo/konf/blob/master/src/main/kotlin/com/uchuhimo/konf/source/Source.kt) to customize your new source, which can be loaded into config by `config.withSource(source)`.
 
+### Strict parsing when loading
+
+By default, Konf extracts desired paths from sources and ignores other unknown paths in sources. If you want Konf to throws exception when unknown paths are found, you can enable `FAIL_ON_UNKNOWN_PATH` feature:
+
+```kotlin
+config.enable(Feature.FAIL_ON_UNKNOWN_PATH)
+    .from.properties.file("server.properties")
+    .from.json.resource("server.json")
+```
+
+Then `config` will validate paths from both the properties file and the JSON resource. Furthermore, If you want to validate the properties file only, you can use:
+
+```kotlin
+config.from.enable(Feature.FAIL_ON_UNKNOWN_PATH).properties.file("/path/to/file")
+    .from.json.resource("server.json")
