 Other foreign key improvements:
 
 - ``ForeignKey`` now exposes ``on_delete`` and ``on_update`` fields reflecting the foreign key's ``ON DELETE``/``ON UPDATE`` actions, and ``table.transform()`` preserves those actions. Previously a transform silently stripped clauses such as ``ON DELETE CASCADE`` from the table schema.
+- ``table.add_foreign_key()`` accepts new ``on_delete=`` and ``on_update=`` parameters for creating foreign keys with actions, e.g. ``table.add_foreign_key("author_id", "authors", "id", on_delete="CASCADE")``. (:issue:`530`)
 - Foreign keys declared as ``REFERENCES other_table`` with no explicit column are now resolved to the other table's primary key by ``table.foreign_keys``, instead of reporting ``other_column=None``.
 - Fixed a ``TypeError`` when sorting ``ForeignKey`` objects where some were compound.

 As with single columns, omitting the other columns will use the compound primary key of the other table. ``other_table`` must always be specified for a compound foreign key.
 
+Use ``on_delete=`` and ``on_update=`` to specify ``ON DELETE`` and ``ON UPDATE`` actions for the foreign key:

+
+    db.table("books").add_foreign_key(
+        "author_id", "authors", "id", on_delete="CASCADE"
+    )
+
+This creates a foreign key with an ``ON DELETE CASCADE`` clause, so deleting an author will also delete their books (provided foreign key enforcement is enabled with ``PRAGMA foreign_keys = ON``). Valid actions are ``"SET NULL"``, ``"SET DEFAULT"``, ``"CASCADE"``, ``"RESTRICT"`` and the default ``"NO ACTION"``.
