+We could use `curl`, but let's use a nicer tool called [httpie][httpie] to test our server. It has much nicer formatting and makes our output easier to read. This is especially useful when testing.
 
-	curl http://127.0.0.1:8000/snippets/
+You can install httpie on all operating systems using pip:
 
-	[{"id": 1, "title": "", "code": "foo = \"bar\"\n", "linenos": false, "language": "python", "style": "friendly"}, {"id": 2, "title": "", "code": "print \"hello, world\"\n", "linenos": false, "language": "python", "style": "friendly"}]

-Or we can get a particular snippet by referencing its id.
+It can also be installed through [Homebrew][brew] on Mac:
 
-	curl http://127.0.0.1:8000/snippets/2/

 We can control the format of the response that we get back, either by using the `Accept` header:
 
-    curl http://127.0.0.1:8000/snippets/ -H 'Accept: application/json'  # Request JSON
