How to deploy to Netlify?

I need to deploy the web part of my universal app to Netlify. Ive tried following the docs to set up continuous integration:

If I use the default settings I get no error messages in the log, however the deployed site just has this message:

Page Not Found

Looks like you’ve followed a broken link or entered a URL that doesn’t exist on this site.

I tried chancing the Base directory to web-build and now the deploy fails with this in the logs:

11:27:34 AM: Failing build: Failed to build site
11:27:34 AM: failed during stage ‘building site’: Deploy directory ‘web-build’ does not exist
