Development

mix setup
mix phx.server

Open http://localhost:4000.

If port 4000 is already in use, you can start the app on the next available port:

sh dev-server.sh

You can also pick a different starting point:

PORT=4010 sh dev-server.sh

If you change any file under config/, restart the server instead of relying on code reloading.
