very slow conda installation

@hikari-murayama @chengren I was helping out one of the geopandas workshops participants briefly today on the frontdesk.... they were having trouble going through the install instructions because it was taking a VERY long time on their 2017 MacBook Air w/8GB of RAM, so we may want to double-check the install process for folks.

As an interim solution, I had them use https://datahub.berkeley.edu/ and they were able to install everything fine there, so that's something to recommend so that people can follow along even if they can't use their own laptop.

We can update this repo to add a 1-click button to get them going in the cloud while they wait for it to install on their laptops.

Thanks @aculich that's really good to know and thanks for trying to work through that with the attendee!!
I definitely think adding that 1-click button would be a great option.
