Steam OpenID strategy for Überauth.

1. Obtain an Steam Web API Key at Steam Dev.

2. Add :ueberauth_steam to your list of dependencies in mix.exs:

   def deps do
     [{:ueberauth_steam, "~> 0.1.2", github: "kouwasi/ueberauth_steam"},]
   end

3. Add the strategy to your applications:

   def application do
     [applications: [:ueberauth_steam]]
   end

4. Add Steam to your Überauth configuration:

   config :ueberauth, Ueberauth,
     providers: [
       steam: {Ueberauth.Strategy.Steam, []}
     ]

5. Update your provider configuration:

   config :ueberauth, Ueberauth.Strategy.Steam,
     api_key: System.get_env("STEAM_API_KEY")

6. Include the Überauth plug in your controller:

   defmodule MyApp.AuthController do
     use MyApp.Web, :controller
     plug Ueberauth
     ...
   end

7. Create the request and callback routes if you haven't already:

   scope "/auth", MyApp do
     pipe_through :browser
   
     get "/:provider", AuthController, :request
     get "/:provider/callback", AuthController, :callback
   end

8. Your controller needs to implement callbacks to deal with Ueberauth.Auth and Ueberauth.Failure responses.

For an example implementation see the Überauth Example application.

Depending on the configured URL you can initialize the request through:

/auth/steam
