+
+This package aims to make easy to automatically run hlint as part of unit tests.
+That means hlint will be run when you execute `cabal test` or `stack test`.
+
+## How to make it work
+
+Hlint-test package contains GHC preprocessor which will generate the code
+containing hlint runner. To invoke the preprocessor, create new test and put
+following line into it:
+
+```
+{-# OPTIONS_GHC -F -pgmF hlint-test #-}
+```
+
+Don't forget to add the test into cabal file (or package.yaml respectively) as
+separated test runner ;).
+
+Now you can run the test simply by `stack test` or `cabal test`.
+
+## Hlint options
+
+If you need to you can use the preprocessor macro to pass some additional
+arguments to the hlint. As it's shown on following line:
+
+```
+{-# OPTIONS_GHC -F -pgmF hlint-test -optF src -optF -r #-}
+```
+
+This will tell hlint to look for source codes only in `src` directory and to 
+generate html report if some suggestions are found.
+
+Also you can use hlint configuration file too ;).
+
+## Example
+
+Simple example of the use can be seen in this package.
