+Quick Start using Stack
+-----------------------
+
+1. Install [Stack](https://www.haskellstack.org/)
+
+2. Download dependencies by running
+
+        $ stack build
+
+2. Then check you can actually run the tests with:
+
+        $ stack runhaskell W0Test.hs
+
+    This should print `Everything seems to be OK!`. If you see any errors,
+    you might not have a problem with your Haskell installation.
+
+3. Generate the exercise templates (files `W*.hs`):
+
+        $ make
+
+4. Now you can edit `W1.hs` and see how well you did by running
+
+        $ stack runhaskell W1Test.hs
+
+Alternative Quick Start using cabal
+-----------------------------------
+
+In case you have problems with `stack`, here is a more old-fashioned
+way to work with the exercises.
 
 1. Install [The Haskell Platform](https://www.haskell.org/platform/)
