@lbianchi-lbl Do you know how I can resolve this notebook failure?

[lbianchi-lbl]

The kernelspec name should be changed to watertap-dev (the same as the existing notebooks). If the environment was set up according to this how-to guide, you should be able to do it directly from the Jupyter(Lab) interface.

This is great, @MarcusHolly ! Good timing as we are aiming to spruce up tutorials and possibly use for upcoming workshops. I am thinking about whether we should bring in #1178 or this first. #1178 adds a landing page for all tutorials, and I repaired/renamed some tutorials that we have now. Maybe this one first, then I can add these new tutorials to the landing page. Thoughts @MarcusHolly @zacharybinger @ElmiraShamlou @kurbansitterley @luohezhiming ?

@adam-a-a I agree - I think we can merge this one first and then update #1178

Great! This is a priority as it may come in handy for upcoming workshop. I did not thoroughly check for typos, so if second reviewer could do that, that would be much appreciated.

LGTM. I did not see any typos.
