+Contains documentation of the `ormar` internal API.
+
+Note that this is a technical part of the documentation intended for `ormar` contributors.
+
+!!!note
+    For completeness as of now even the internal and special methods are documented and exposed in API docs.
+
+!!!warning
+    The current API docs version is a beta and not all methods are documented, 
+    also some of redundant items are included since it was partially auto generated.
+
+!!!danger
+    Ormar is still under development, and the **internals can change at any moment**.
+
+    You shouldn't rely even on the "public" methods if they are not documented in the 
+    normal part of the docs.
