Could not start application apns: exited in: APNS.start(:normal, [])

It seems that the documentation is incomplete.

I tried the config with my updated infos in the README example without success it seems that the apns config needs a pools section. Can you update the README.md ?

** (Mix) Could not start application apns: exited in: APNS.start(:normal, [])
    ** (EXIT) an exception was raised:

Hi, thanks for reporting. I just created an issue in the apns library to see if we can get around this without requiring the user to add any extra configuration. I will updated the README if I cannot get this patch merged.

I will keep this issue open until I get an answer, in the meanwhile, you can add

config :apns,
  pools: []

to your config.exs to fix the issue.
