 ### Usage
 
-Backoff is a `time.Duration` counter. It starts at `Min`. After every call to `Duration()` it is  multiplied by `Factor`. It is capped at `Max`. It returns to `Min` on every call to `Reset()`. Used in conjunction with the `time` package.

It returns to `Min` on every call to `Reset()`. `Jitter` adds randomness ([see below](#exampleusingjitter)). Used in conjunction with the `time` package.
