 ### Functions for working with Pairs
-```
-use function Pairs\cons;
-use function Pairs\car;
-use function Pairs\cdr;
-use function Pairs\toString;
-```
+
+    use function Pairs\cons;
+    use function Pairs\car;
+    use function Pairs\cdr;
+    use function Pairs\toString;
 
 ### Functions for working with Lists
-```
-use function Lists\length;
-use function Lists\reverse;
-use function Lists\map;
-use function Lists\filter;
-use function Lists\reduce;
-```
-### example
-\# 1
-```
-$pair = cons(1, 2);
-
-$one = Pairs\car($pair); // $one = 1;
-$two = Pairs\cdr($pair) // $two = 2;
-```
-\# 2
-```
-$list = cons(1, cons(2, cons(3, cons(4, cons(5, cons(6, null))))));
-$length = length($list); // $length = 6;
-
-$filter = filter(function ($x) {
-    return $x % 2 == 0;
-}, $list);
-$result = toString($filter); \\ $result = "(2, 4, 6)";
