For holidays to be visible in the holiday calendar it is worth mentioning that the reply must content a timestamp that you add from the editors menu.
Also as it was previously state the id of the post is found by adding .json to the url of the post. I think this should be added to the documentation here as if categories have their id in the url the topic url id will confuse people as its number may be close but not similar to the real topic id.
Thank you for this guide anyway, there is a lot to cover because there are many features which is cool, great job devs !
