+## Obtaining CTA API keys
+
+You need to obtain API keys to access CTA data. The API keys are two separate keys for two services.
+
+- [Bus API](http://www.transitchicago.com/developers/bustracker.aspx)
+- [Train API](http://www.transitchicago.com/developers/traintrackerapply.aspx)
+
+The bus tracker API key can be obtained immediately, the train tracker key can take a few days to register.

+
+```js
+{
+  stops: [
+    {
+      type: 'bus',
+      id: 561,
+      name: 'Chicago and Milwaukee'
+    },
+    {
+      type: 'train',

+    }
+  ]

+| -------- | -------------------------------------------------------------------- |
+| `type`   | Type of stop. Either `bus` or `train`                                |
+| `id`     | Stop ID. See [Finding Stop IDs](#finding-stop-ids)                   |
+| `name`   | Name of stop. This is displayed in the header of the stop's results. |
+
+### Finding Stop IDs
+
+1. Go to [CTA Trackers](https://www.transitchicago.com/tracker/) and select Train or Bus Tracker.
+2. Search for your stop inside of the given app
+3. Once you find your stop, obtain the Id. It will be the number at the end of the page's URL
+   1. For train tracker, it may look like `?sid={id}`. The `id` is the stop ID.
+   2. For bus tracker, it may look like `Southbound/{id}`. The `id` is the stop ID.
