Any up-to-date tutorial for the flexbox module? [closed]

Question

I know the Flexible Box Layout module spec has changed, and some browsers now implement more than one version of it (using different syntaxes). I've been searching for information, but I can only find tutorials with warnings that they're now out of date.

I know the spec might change again, but I have an unusual use case (a Chrome extension) and I want to use it in its current form. I just want to know how to use the latest version implemented in Chrome.

Does anyone know of an up-to-date tutorial?

Here is the best flexbox tutorial I have found so far, it is very well explained or if you need a deeper explanation check the w3c draft.

And for testing and better understanding of the flexbox model, check this flexbox playground.
