I've got a free application located on Heroku, along with a domain on register.com. How do i connect the 2? I'm Comfortable with using any service or addon, as lengthy because it is free. The only real agreement is will be able to not spend Anything. I should also have the ability to come with an m subdomain for any mobile site. Thanks

Do as instructed to configure custom domain names.

You need to simply install the free custom_domain names addon.

$ heroku addons:add custom_domain names

Adding the domain names

$ heroku domain names:add world wide web.example.com

Then, be sure to update the DNS configurations in your domain provider to suggest to Heroku IP.
