This project is built using sbt on the jvm, though produces both jvm and js artifacts.
As the most-recent built artifacts are committed to './docs/demo/*', you can immediately run the code in your browser just by opening open ./docs/demo/index.html:
open ./docs/demo/index.html
You can update the github demo page using a custom sbt demo task (which just compiles the relevant code copies it to ./docs/demo/), then manually commit/push those changes:
sbt demo
git commit -am 'made some updates'
git push origin
Typically, however, you would want to immediately compile/update the local site as you make changes, in which case
you would tell sbt to continually compile the javascript code (e.g. the 'riffJS' subproject) and then open/refresh ./local-test.html:
open ./local-test.html <-- open this in a browser
sbt
project riffJS
