i don't know if it's related application or related modifications made integrating universal. doesn't work , don't find online problem.

i tried angular cli 1.1.3, 1.2.7 , 1.3. last 1 should integrate universal support. followed related tutorial here https://github.com/angular/angular-cli/wiki/stories-universal-rendering

but doesn't explain how run entire project. says 2 folders created , there code should used test , output html console, it's not need. need run in browser.

can me please?
