-[Arbitrary] Instances for [Network][network-category] Types
+[Homepage](https://github.com/alunduil/network-arbitrary)
+By Alex Brandt <alunduil@gmail.com>
 
-I am providing code in the repository to you under an open source license.
-Because this is my personal repository, the license you receive to my code is
-from me and not my employer (Facebook).
+## Description
 
-# Getting Started
+You can use network-arbitrary to provide Arbitrary instances for Network module types.
 
-Documentation is available on [Hackage].  A great guide to [QuickCheck] is
-<https://begriffs.com/posts/2017-01-14-design-use-quickcheck.html>.
+## Terms of use
 
-# Reporting Issues
+You are free to use network-arbitrary without any conditions.  See the [LICENSE]
+file for details.
 
-Any issues discovered should be recorded on [github][issues].  If you believe
-you've found an error or have a suggestion for a new feature; please, ensure
-that it is reported.
+## How to use network-arbitrary
 
-If you would like to contribute a fix or new feature; please, submit a pull
-request.  This project follows [git flow] and utilizes [travis] to automatically
-check pull requests before a manual review.
+```haskell
+{-# LANGUAGE TypeApplications #-}
+module main where
 
-# Contributors
+import Network.URI (URI)
+import Network.URI.Arbitrary ()
 
-The `COPYRIGHT` file contains a list of contributors with their respective
-copyrights and other information.  If you submit a pull request and would like
-attribution; please, add yourself to the `COPYRIGHT` file.
