 ## Step 6 - Check out workflows, experiences and advices
 
 There are some workflows to be aware of and we collected some advice and experiences that you might find useful:
 
 - Every change you make should be reviewed by another member of your language team. You might need to press the `Unreview` button after changing a reviewed item.
 - For each item you translate/review you can add comments including mentioning other members using `@name`.
