Telegram Bot API Wrapper written in Elixir ([document](https://hexdocs.pm/nadia/))

## Installation
Add Nadia to your `mix.exs` dependencies:

```elixir
def deps do
  [{:nadia, "~> 0.4.1"}]
end
```
and run `$ mix deps.get`.

## Configuration

In `config/config.exs`, add your Telegram Bot token like [this](config/config.exs.example)

```elixir
config :nadia,
  token: "bot token"
```

You can also add an optional recv_timeout in seconds (defaults to 5s).
```elixir
config :nadia,
  recv_timeout: 10
```

And then, in `mix.exs`, list `:nadia` as an application inside `application/0`:

```elixir
def application do
  [applications: [:nadia]]
end
```

Now Mix will guarantee the `:nadia` application is started before your application is started.
