Tutorial revision + Spanish translation

Hello folks, we've been thinking that it would be a good idea to have an Spanish version of the tutorial. But before starting the translation efforts we were wondering if we want to do a tutorial revision.

The reason I asked this is because I noticed that the tutorial is designed to be delivered by someone who fills in the gaps as the tutorial goes live or via video, but if someone is following the notebooks by themselves, there are certain parts where the material doesn't feel self contained. We also have examples that are not working (For example, the recently issue report #213 )
What do we think about this, what is the best way to update the tutorial and what do we want in it?

Regarding the Spanish translation I'll be happy to take the lead on it, I'd like to know if there are more people in the dask community that speaks Spanish and that could potentially help.

Start by reviewing the tutorial notebooks and the broken example referenced in issue #213. Identify which material is not self-contained and which examples need correction, then document an agreed revision scope before beginning the Spanish translation. Done means the revision plan and translation approach are decided.
