+# Overview
 rsling is a Go HTTP client library for creating and sending API requests.
 
 rslings store HTTP Request properties to simplify sending requests and decoding responses. Check [usage](#usage) or the [examples](examples) to learn how to compose a rsling into your API client.
 
 **Fair Notice:** rsling started its life as a normal fork of the already popular and awesome
-[sling](https://github.com/dghubble/sling). However overtime I noticed for some reason PRs like this and this
-etc. were not being entertained at all for unknown reasons hence I decided to make this repo into a hard/detached
-fork and go my separate way so that exciting new features and improvements can be added without hinderance. Having
-said that I would like to give a big thanks to the contributors and owners of the sling repository because
-without them this package could not have existed.
