How to change heroku project name and root url

[Vitor Freire]

Hi Chris,

I have created a new app with an intuitive name for myself (for development purposes). But I realized that participants will be able to figure it out in the URL, so I need to change it. How can I do it?

click on the app here  here: https://dashboard.heroku.com/apps 

Then go to the settings section (I think) and you can change the name there.
