 ## Usage
 
-### Compiler wrapper mode

-This new mode is recommended as CWhy will then operate in the same context as the compiler, and will do a better job
-finding the right source files.
+The wrapper mode is now default and mandatory, with a slightly modified interface.
+CWhy can either be used standalone by passing the full command after the triple dashes `---`, or as part of a build tool
+by creating a short executable script wrapping the compiler command.
 
 ```bash
 # Invoking the compiler directly.
-% `cwhy --wrapper` mycode.cpp

-# Using fix mode.
-% `cwhy --wrapper fix` mycode.cpp
+% cwhy --- g++ mycode.cpp
 
-# Using cwhy with Java.
