+# Core Actions Reference
+
+Core Actions are primitives implemented by the Dagger Engine itself. They can be combined into higher-level composite actions. Their definitions can be imported in the `dagger.io/dagger/core` package.
+
+For more information about Dagger Actions, see [Dagger Actions](../core-concepts/1221-action).
+
+The following core actions are available:
+
