 When you have a lot of issues, it can be hard to get an overview.
 By adding a weight to each issue, you can get a better idea of how much time,
 value or complexity a given issue has or will cost.
 
 You can set the weight of an issue during its creation, by simply changing the
-value in the dropdown menu. You can set it to a numeric value from 1 to 9.
+value in the dropdown menu. You can set it to a non-negative integer
+value from 0, 1, 2, and so on. You can remove weight from an issue
+as well.
 
 This value will appear on the right sidebar of an individual issue, as well as
 in the issues page next to a distinctive balance scale icon.
