-# Exponential Backoff [![GoDoc][godoc image]][godoc] [![Coverage Status][coveralls image]][coveralls]
-
-This is a Go port of the exponential backoff algorithm from [Google's HTTP Client Library for Java][google-http-java-client].
-
-[Exponential backoff][exponential backoff wiki]
-is an algorithm that uses feedback to multiplicatively decrease the rate of some process,
-in order to gradually find an acceptable rate.
-The retries exponentially increase and stop increasing when a certain threshold is met.
-
-## Usage
-
-Import path is `github.com/cenkalti/backoff/v4`. Please note the version part at the end.
-
-Use https://pkg.go.dev/github.com/cenkalti/backoff/v4 to view the documentation.
-
-## Contributing
-
-* I would like to keep this library as small as possible.
-* Please don't send a PR without opening an issue and discussing it first.
-* If proposed change is not a common use case, I will probably not accept it.

-ExponentialBackOff is a backoff implementation that increases the backoff
-period for each retry attempt using a randomization function that grows exponentially.
-
-NextBackOff() is calculated using the following formula:
-
- randomized interval =
-     RetryInterval * (random value in range [1 - RandomizationFactor, 1 + RandomizationFactor])
-
-In other words NextBackOff() will range between the randomization factor
-percentage below and above the retry interval.
-
-For example, given the following parameters:
-
- RetryInterval = 2
- RandomizationFactor = 0.5
- Multiplier = 2
-
-the actual backoff period used in the next retry attempt will range between 1 and 3 seconds,
-multiplied by the exponential, that is, between 2 and 6 seconds.
-
-Note: MaxInterval caps the RetryInterval and not the randomized interval.
-
-If the time elapsed since an ExponentialBackOff instance is created goes past the
-MaxElapsedTime, then the method NextBackOff() starts returning backoff.Stop.
-
-The elapsed time can be reset by calling Reset().
-
-Example: Given the following default arguments, for 10 tries the sequence will be,
-and assuming we go over the MaxElapsedTime on the 10th try:
-
- Request #  RetryInterval (seconds)  Randomized Interval (seconds)
