+    # A Word of Caution
+
+    This API was designed for internal use only, and the design doesn't comply with the resources convention of a RESTful API. Because of this, most of the API endpoints listed here will soon be updated and removed in future versions of Mango, so use them at your own risk!
+
+    # Authentication
+
+    All endpoints require authentication. After logging in, your session ID would be stored as a cookie named `mango-sessid-#{Config.current.port}`, which can be used to authenticate the API access. Note that all admin API endpoints (`/api/admin/...`) require the logged-in user to have admin access.
+
+    # Terminologies
+
+    - Entry: An entry is a `cbz`/`cbr` file in your library. Depending on how you organize your manga collection, an entry can contain a chapter, a volume or even an entire manga.
+    - Title: A title contains a list of entries and optionally some sub-titles. For example, you can have a title to store a manga, and it contains a list of sub-titles representing the volumes in the manga. Each sub-title would then contain a list of entries representing the chapters in the volume.
+    - Library: The library is a collection of top-level titles, and it does not contain entries (though the titles do). A Mango instance can only have one library.
