+ARF has a collection of basic control flow [phrases](Phrases) which are `break`, `next`,
+and `return`. Break breaks out of a loop or switch case, next is basically just
+a continue statement but using less letters, and a return phrase returns from
+the current function. Return phrases are entirely optional and do not take any
+arguments.
+
+ARF also has some control flow phrases that expect an indented block of phrases
+under them:
+
+```
+if condition
+	something
+
+if condition
+	something
+else
+	otherThing
+
+while condition
+	something
+
+switch value
+: 324
+	something
+: 93284
+	otherThing
+:
+	defaultThing
+
+for index:Size element:Int someArray
+	something
+```
+
+These do what you'd expect them to, but for loops in ARF need some further
+explanation. Many modern languages allow you to iterate over data, and ARF is no
+exception. The first [argument](Arguments) of a for loop must be an index of type `Size`, the
+second argument must be typed as an element of the third argument, which must
+be an array or inherit from an array. In the future there might be some
+iterateable [interface](Interface-Definitions) that an object could fulfil.
