+### Vertical spacing
+
+Runic removes empty vertical spacing so that there are at maximum two empty lines between
+expressions. Examples:
+```diff
+-function f()
+-     x = 1
+-
+-
+-
+-    return x
+-end
++function f()
++     x = 1
++
++
++    return x
++end
+```
+
 ### Spaces around operators, assignment, etc
 
 Runic formats spaces around infix operators, assignments, comparison chains, and type
