+## About
+
+This rule enforces the following:
+
+- Restrict iterator variable names. `for` loop iterator variables should be named `i`. Nested loops should use the variables `j`, `k`, and so on.
+- Restrict loop nesting.  You can restrict the maximum nesting of `for` loops. By default, this limit is three.
+- Prevent postfix increment and decrement operators. The hapi style guide does not allow postfix increment and decrement operators in `for` loop updates. The prefix version of these operators should be used instead.
+- Single variable declaration in initialization section. A single `var i = 0;` is allowed in the initialization section. This only applies to variable declarations, not assignments to existing variables. This means that `for (i = 0, j = 0)` is allowed if `i` and `j` are existing variables. Variable declarations involving destructuring are not allowed.
+
+## Rule options
+
+This rule can be configured by providing a single options object. The object supports the following keys.
+
+### `maxDepth`
+
+A number representing the maximum allowed nesting of `for` loops. Defaults to three.
+
+### `startIterator`
+
+The first variable iterator name to use. This defaults to `'i'`.
