Facebook Instant Game index.html file problem

So I am currently trying to make a Facebook Instant Game, and when I open the index.html file from the fbinstant package, the editor doesn’t return anything but a black uneditable screen:

Am I forgetting something or is this a bug?

Thanks in advance for the help!

We load and show .html files in the editor and render their content. And the index.html that you are opening will not be able to load the game like that. You need to do Project->Build HTML5 or Project->Bundle->HTML5 and upload and test or test it locally.

Oh okay. Does that mean that if I want to edit it, I need to bundle it to HTML5 and change it in another editor than Defold? Sorry if I’m asking simple questions by the way, I’m a bit of a newbie.

If you want to edit the index.html you need to make a copy of it into your own project, edit it using an external editor (Atom, Sublime, Notepad etc). You also need to open game.project and make sure to point to your changed version down in the HTML section.
