Basic installation examples failing

[ulyngs]

• Mirador version (release, commit, etc.):

Hi there,

my collaborators and I are unable to get the basic Mirador 3 installation instructions to work.

Codesandbox

The basic setup example at codesandbox.io fails to load: https://codesandbox.io/s/mirador-plugin-example-pgg5k?file=/index.html

README.md

When installing mirador in a directory with npm install mirador and then running npm start, I simply get this list of errors:

npm ERR! Missing script: "start"
npm ERR!
npm ERR! Did you mean one of these?
npm ERR!     npm star # Mark your favorite packages
npm ERR!     npm stars # View packages marked as favorites
npm ERR!
npm ERR! To see a list of scripts, run:
npm ERR!   npm run

npm ERR! A complete log of this run can be found in:
npm ERR!     /Users/ulyngs/.npm/_logs/2021-12-22T07_50_10_469Z-debug.log

Are we missing something basic?

Some of the answers to my troubles are explained in this google doc - perhaps this can be linked to on the readme, to reduce frustration for newbies like myself who come to the github repo and just look for how to make the basics work? :)
