+To start your Phoenix server:
+
+ * Run `mix setup` to install and setup dependencies
+ * Start Phoenix endpoint with `mix phx.server` or inside IEx with `iex -S mix phx.server`
+
+Now you can visit [`localhost:4000`](http://localhost:4000) from your browser.
+
+Ready to run in production? Please [check our deployment guides](https://hexdocs.pm/phoenix/deployment.html).

+ # `:keyfile` and `:certfile` expect an absolute path to the key

+ # "priv/ssl/server.key". For all supported SSL configuration
+ # options, see https://hexdocs.pm/plug/Plug.SSL.html#configure/1

+ #
+ # config :munch, MunchWeb.Endpoint,
+ # force_ssl: [hsts: true]
+ #
+ # Check `Plug.SSL` for all available options in `force_ssl`.
+
+ # ## Configuring the mailer
+ #
+ # In production you need to configure the mailer to use a different adapter.
+ # Also, you may need to configure the Swoosh API client of your choice if you
+ # are not using SMTP. Here is an example of the configuration:
+ #
+ # config :munch, Munch.Mailer,
+ # adapter: Swoosh.Adapters.Mailgun,
+ # api_key: System.get_env("MAILGUN_API_KEY"),
+ # domain: System.get_env("MAILGUN_DOMAIN")
+ #
+ # For this example you need include a HTTP client required by Swoosh API client.
+ # Swoosh supports Hackney, Req and Finch out of the box:
+ #
+ # config :swoosh, :api_client, Swoosh.ApiClient.Hackney
+ #
+ # See https://hexdocs.pm/swoosh/Swoosh.html#module-installation for details.
