 in any module if you want to use the `Async` module for instance and compile your code using the `--include` option of `sjw` with package `unitJS` :
 
 ```
-sjw -I unitJS your/code/src -o your/code/main.js
+$ sjw -I unitJS your/code/src -o your/code/main.js
 ```
 
 Note that all modules have their path prefixed by a common `UnitJS` component and that SJW will only include the modules actually used in your code, not all of UnitJS.
