 ## Remarks
 
-When **/hotpatch** is used in a compilation, the compiler ensures that first instruction of each function is at least two bytes, which is required for hot patching.
+When **/hotpatch** is used in a compilation, the compiler ensures that first instruction of each function is at least two bytes, and there's no jump to the first instruction from within the function, which is required for hot patching.
 
 To complete the preparation for making an image hotpatchable, after you use **/hotpatch** to compile, you must use [/FUNCTIONPADMIN (Create Hotpatchable Image)](functionpadmin-create-hotpatchable-image.md) to link. When you compile and link an image by using one invocation of cl.exe, **/hotpatch** implies **/functionpadmin**.
