 At this stage, we're still exploring ourselves which kind of levels would be fun! So feel free to try new things: basic introductions with a little story? Really hard puzzles? Levels where you have to find information? Levels where you need to fix a problem? Levels with three remotes?
 
+## Add localizations
+1. Add the localization text into the section "description" in the  file ./resource/cards.json
+   Example:
+       "description": {
+          "en_EN": "Drag this card into the empty space above to initialize the time machine!",
+	  "it_IT": "Trascina questa carta nell'area vuota sopra per inizializzare la macchina del tempo",
+	  "es_ES": ""
+       }
+2. Add, into the directory *levels*, the directory with the levels to you want to adding (es. ./levels/fr_FR/LIVELLI )
+1. Add, the localization into the dictionary game.langs (es. var langs = {0: "en_EN", 1: "it_IT", 2: "es_ES"} the first and default localization it must be en_EN

 To open the game in the [Godot editor](https://godotengine.org), run `godot project.godot`. You can then run the game using *F5*.
