## Installation

If you have a clean, recent installation of Phoenix, you should already have Tailwind installed.

### Install MBTA METRO

Add this to your `mix.exs`:

```elixir
def deps do
  [
    {:mbta_metro, ">= 0.0.0"}
  ]
end
```

Import the styles in your `assets/css/app.css`:

```css
@import "../../deps/mbta_metro/priv/static/assets/app.css";
```

The, follow the installation instructions for the [npm package](https://www.npmjs.com/package/mbta_metro).

### LiveComponents

Some components, like the Map, take further configuration.

#### Map

```elixir
config :mbta_metro, :aws_location,
  api_key: System.get_env("AWS_LOCATION_API_KEY"),
  map_name: System.get_env("AWS_LOCATION_MAP_NAME"),
  region: System.get_env("AWS_LOCATION_REGION")
```

You'll also have to add the following to your CSP (assuming you have one):

```elixir
[
  "child-src blob: ;",
  "connect-src *.amazonaws.com",
  "worker-src blob: ;"
]
```
