 ## features
   * axios - the most used package for http requests in npm.
-  * promise based - most of us using the current http module and on every call do `.toPromise()`
-    because most of the time we do not need the features of observable.
-  * retries - one of the powerful features of observable is its ability to do in very simple way,
-    you can do it by just adding the retry operator, this package will provide you the same feature even in easier way,
-    just pass `{ retries: NUMBER_OF_RETRIES }` in the config of the http module.
+  * promise based - most of us using the current http module that uses observable which we don't use most of the time

+  * retries - in many cases we will want to retry a failing http call.
+    with observable we could just add the retry operator (rxjs) but with promises we need to implement this logic ourselves.
+    this package will make it easy for you, just pass `{ retries: NUMBER_OF_RETRIES }` in the config of the http module.
