+### Converting existing code
+
+If you want to uniformly use flow operators you can use [HLint] with the
+`hlint-flow.yaml` file. For easy use, it is best to extract the 
+`hlint-flow.yaml` to your project directory and do
+
+``` sh
+> hlint -h hlint-flow.yaml <source file>  
+```
+
+or
+
+``` sh
+> hlint --git -h hlint-flow.yaml
+```
+
+to check all Haskell source tracked by git.
+
 For more information about Flow, please read [the Haddock documentation][].
