+
+Retries a function that returns a promise, leveraging the power of the [retry](https://github.com/tim-kos/node-retry) module to the promises world.
+
+There's already some modules that are able to retry functions that return promises but
+they were rather difficult to use or do not offer an easy way to do conditional retries.
+
+
+## Installation
+
+`$ npm install promise-retry`
+
+
+## Usage
+
+### promiseRetry(fn, [options])
+
+Calls `fn` until the returned promise ends up fulfilled or rejected with an error different than
+a `retry` error.   
+The `options` argument is an object which maps to the [retry](https://github.com/tim-kos/node-retry) module options:
+
+- `retries`: The maximum amount of times to retry the operation. Default is `10`.
+- `factor`: The exponential factor to use. Default is `2`.
+- `minTimeout`: The number of milliseconds before starting the first retry. Default is `1000`.
+- `maxTimeout`: The maximum number of milliseconds between two retries. Default is `Infinity`.
+- `randomize`: Randomizes the timeouts by multiplying with a factor between `1` to `2`. Default is `false`.
+
+
+The `fn` function will receive a `retry` function as its first argument that should be called with an error whenever you want to retry `fn`. The `retry` function will always throw an error.   
+If there are retries left, it will throw a special `retry` error that will be handled internally to call `fn` again.
+If there are no retries left, it will throw the actual error passed to it.
+
+If you prefer, you can pass the options first using the alternative function signature `promiseRetry([options], fn)`.
+
+## Example
+```js
+var promiseRetry = require('promise-retry');
+
+// Simple example
+promiseRetry(function (retry, number) {
+    console.log('attempt number', number);
+
+    return doSomething()
+    .catch(retry);
+})
+.then(function (value) {
+    // ..
+}, function (err) {
+    // ..
+});
+
+// Conditional example
+promiseRetry(function (retry, number) {
+    console.log('attempt number', number);
+
+    return doSomething()
+    .catch(function (err) {
+        if (err.code === 'ETIMEDOUT') {
+            retry(err);
+        }
+
+        throw err;
+    });
+})
+.then(function (value) {
+    // ..
+}, function (err) {
+    // ..
+});
+```
