         Map a PE format file into memory like Windows LoadLibrary() would do.
         Doesn't apply base relocations if the function is relocated.
 
+        There are two scenarios:
+
+        - image could be preloaded and then MAPMapPEFile is called for it
+        - image is loaded with MAPMapPEFile
+
+        In the first scenario, hFile and lpPreloadedBase are supposed to be NULL, and szPath and size - non-NULL.
+        In the second scenario, hFile and lpPreloadedBase are supposed to be non-NULL, and szPath and size - NULL.
+
+        See coreclr_preload_assembly for further details.

     Parameters:
         IN hFile - file to map
+        IN szPath - path to mapped file
+        OUT size - mapped virtual size
+        IN lpPreloadedBase - previously loaded base
 
     Return value:
         non-NULL - the base address of the mapped image
         NULL - error, with last error set.
