+### Loops
+
+The `loop` block can be configured (based on weather or not each boolean statement is omitted) to act as any type of loop.
+
+The *first* conditional is the **initial run condition**.  It decides weather the loop is entered at all.  If omitted, defaults to `true`, creating a `do ... while` type block.
+
+The *second* conditional is the **subsequent run condition**. It decides weather the loop continues to loop or not.  If omitted, it *mirrors* the **initial run condition** (this is equivalent to a `for` or `while` block).
+
+Examples:
+	
+	# Same as a do ... while block
+	/; loop [ <conditional> ]
+		<statements>
+	;/
+
+	# Same as a while loop
+	/; loop ( <conditional> )
+		<statements>
+	;/
+
+	# Infinite loop
+	/; loop
+		<statements>
+	;/
+
+	# Adding statements to mimic a for loop
+	/; loop (int i = 0; i < 10) [i++]
+		<statements>
+	;/
