@@ -180,12 +180,31 @@ A plugin is an interface whose methods get called during key events in a request
 - `OnRequestStart` is called just before the request is made
 - `OnRequestEnd` is called once the request has successfully executed
 - `OnError` is called is the request failed
+- `NextInterval` is called the request retry mechanism
 
 Each method is called with the request object as an argument, with `OnRequestEnd`, and `OnError` additionally being called with the response and error instances respectively.
-For a simple example on how to write plugins, look at the [logger plugin](/plugins/logger.go).

+### Creating an HTTP client with a plugin retry mechanism
+
+```go
+client := httpclient.NewClient(&httpclient.Config{
+	Name:                         	"test",
+	BaseUrl:                      	"https://webhook.site",
+	ConsiderServerErrorAsFailure: 	true,
+	ServerErrorThreshold:         	500,
+	RetryCount:						5
+})
+
+// Create a new retry mechanism with the backoff
+retrier := plugins.NewRetrier(plugins.NewConstantBackoff(1*time.Second, 1))
+// Create a new client, sets the retry mechanism, and the number of times you would like to retry
+client.AddPlugin(retrier)
