title: How can I configure nginx to use 2 docroots (with different hostnames) with ddev
body: <p>I want to use 2 web sites inside a ddev web container but can't find out how to configure nginx the right way.
  I have set up the additional_hostname to site-a and site-b to let me access the web site with site-a.ddev.site and site-b.ddev.site. The web sites are in different local directories site-a and site-b.</p>
  
  <p>How can I define the "sites-available" and "sites-enabled" configuration for nginx?
  In the documentation I found only the way to create a .ddev/nginx-site.conf file, but with this I can only configure one web site.</p>
  
  <p>I know that I can "ddev ssh" into the container and configure it by hand, but it should configure automatic when I checkout the project and made a "ddev configure" and "ddev start".</p>
