 ## How to use?
 
-### Play Interactively
+If you are new to Julia or reinforcement learning, you can preview the
+[notebooks](https://juliareinforcementlearning.org/ReinforcementLearningAnIntroduction.jl/) first. (Credit goes to [Andrea PIERRÉ](https://github.com/kir0ul))
 
 For experienced users with the latest stable Julia properly installed:
 
 1. Clone this project.
 1. Start the Julia REPL under the folder you created above.
 1. Install [Pluto.jl](https://github.com/fonsp/Pluto.jl)
-  1. `] add Pluto`
-  1. `using Pluto`
-  1. `Pluto.run()`
+    1. `] add Pluto`
+    1. `using Pluto`
+    1. `Pluto.run()`
 1. Now you can see the Pluto page is opened in your browser. Paste
    `notebooks/Chapter01_Tic_Tac_Toe.jl` (or any other file under the `notebooks` folder) into
    the input box and click the `Open` button.
