-Get GTFS for Transit Schedules and Stops
+Clone this repo to your machine.

+git clone https://github.com/ikespand/docker-otp
+cd docker-otp

 ```
 
-Get OSM extract for Streets

+```shell

+Alternatively, modify the `docker-compose.yml` and then execute:
+```shell
+docker-compose up
+```
 The graph build operation should take about one minute to complete, and then you'll see a Grizzly server running message. At this point you have an OpenTripPlanner server running locally and can open http://localhost:8080/ in a web browser. You should be presented with a web client that will interact with your local OpenTripPlanner instance.
 
 This map-based user interface is in fact sending HTTP GET requests to the OTP server running on your local machine. It can be informative to watch the HTTP requests and responses being generated using the developer tools in your web browser.
 
-### Usage
+### Resources
 
 There are a number of different resources available through the HTTP API. Besides trip planning, OTP can also look up information about transit routes and stops from the GTFS you loaded and return this information as JSON. For example:
