+## Running and exporting
+
+There are two scripts:
+
+```
+./server.sh
+```
+
+This one starts a HTML server (via browsersync) that shows the `game`
+directory, where game can be exported.
+
+```
+./export.sh
+```
+
+This one rebuilds the game, provided that you have `godot` in your PATH.
+It exports the HTML5 preset into the `game` directory, which triggers browser
+reload.
