+# Internet Archive #
+
+There's also a helper for loading software from [the Internet Archive](https://archive.org/v2), `IALoader`. IALoader looks at the metadata associated with their items and uses that to build the configuration for the emulator.
+
+## Examples ##
+
+    var emulator = IALoader("#canvas", "atari_2600_pitfall_1983_cce_c-813/atari_2600_pitfall_1983_cce_c-813.bin");
