+If you have any installation issues, please open an issue.
 
 ## Fetching Websites
-Fetchers are basically interfaces that do requests or fetch pages for you in a single request fashion and then return an `Adaptor` object for you. This feature was introduced because the only option we had before was to fetch the page as you wanted it, then pass it manually to the `Adaptor` class to create an `Adaptor` instance and start playing around with the page.
+Fetchers are interfaces built on top of other libraries with added features that do requests or fetch pages for you in a single request fashion and then return an `Adaptor` object. This feature was introduced because the only option we had before was to fetch the page as you wanted it, then pass it manually to the `Adaptor` class to create an `Adaptor` instance and start playing around with the page.
 
 ### Features
 You might be slightly confused by now so let me clear things up. All fetcher-type classes are imported in the same way
