 This describes the debug version of *hello-world*, configured by setting the
-`"DEBUG"` flag, which in turn will instruct the updated toolchain defaults,
-which now honor the `"DEBUG"` argument, to compile all actions with the `"-g"`
-flag.
+`"DEBUG"` map to enable regular (non-fission) debug mode, which in turn will
+instruct the updated toolchain defaults, which honor the `"DEBUG"` argument, to
+compile all actions with the `"-g"` flag.
 
 To actually collect the artifacts needed to run the debugger, we use the
 `["CC", "install-with-deps"]` rule, contained in the `rules-cc` repository.
