## Installation

If [available in Hex](https://hex.pm/docs/publish), the package can be installed
by adding `firebase_admin` to your list of dependencies in `mix.exs`:

```elixir
def deps do
  [
    {:firebase_admin, "~> 0.1.0"}
  ]
end
```

## Configuration

Add `Goth` to your supervision tree. Example:
```elixir
defmodule MyApp.Application do
  use Application

  @impl true
  def start(_type, _args) do
    service_account = System.fetch_env!("GOOGLE_APPLICATION_CREDENTIALS") |> File.read!() |> Jason.decode!()
    children = [
      {Goth, name: FirebaseAdmin.Goth, source: {:service_account, service_account, []}}
    ]

    Supervisor.start_link(children, strategy: :one_for_one)
  end
end
```

See the [Goth repo](https://github.com/peburrows/goth/tree/master) for more info. 
**Note:** FirebaseAdmin currently uses HEAD version of Goth in preparation for the v1.3.0 release.
