+# Core API
+
+This folder contains the Core API. A Core instance is used as a standardized
+API for interfacing with internal classes/modules. Different Cores can be used
+interchangeably with the [Yomikun API](../api/readme.md) for providing the API
+over various types of connections.
+
+Currently implemented cores:
+
+- HTTP
+- Direct
