+Bundled Instructions
+^^^^^^^^^^^^^^^^^^^^
+
+The syntax for bundled instructions is the following:
+
+.. code-block:: text
+
+    BUNDLE implicit-def %r0, implicit-def %r1, implicit %r2 {
+      %r0 = SOME_OP %r2
+      %r1 = ANOTHER_OP internal %r0
+    }
+
+The first instruction is often a bundle header. The instructions between ``{``
+and ``}`` are bundled with the first instruction.
