+# The REST API
+
+Patchwork provides a REST API. This API can be used to retrieve and modify
+information about patches, projects and more.
+
+**NOTE:** The REST API was introduced in Patchwork v2.0. Users of earlier
+Patchwork versions should instead refer to the [XML-RPC API
+documentation][doc-xmlrpc].
+
+## Patchwork REST API documentation
+
+Patchwork provides automatically generated documentation for the RESET API.
+You can find this at the following URL:
+
+ http://patchwork.example.com/api/
+
+where `patchwork.example.com` refers to the URL of your Patchwork instance.
+
+## Interacting with the API
+
+REST APIs run over plain HTTP(S), thus, the API can be interfaced using
+applications or libraries that support this widespread protocol. One such
+application is [`curl`][ref-curl], which can be used to both retrieve and send
+information to the REST API. For example, to get the version of the REST API
+for a Patchwork instance hosted at `patchwork.example.com`, run:
+
+ $ curl -s http://localhost:8000/api/1.0/ | python -m json.tool
+ {
+ "patches": "http://localhost:8000/api/1.0/patches/",
+ "people": "http://localhost:8000/api/1.0/people/",
+ "projects": "http://localhost:8000/api/1.0/projects/",
+ "users": "http://localhost:8000/api/1.0/users/"
+ }
+
+In addition, a huge variety of libraries are avaiable for interacting with and
+parsing the output of REST APIs. The [`requests`][ref-requests] library is
+wide-spread and well-supported. To repeat the above example using `requests`:
+
+ $ python
+ >>> import json
+ >>> import requests
+ >>> r = requests.get('http://patchwork.example.com/api/1.0/')
+ >>> print(json.dumps(r.json(), indent=2))
+ {
+ "users": "http://localhost:8000/api/1.0/users/",
+ "patches": "http://localhost:8000/api/1.0/patches/",
+ "projects": "http://localhost:8000/api/1.0/projects/",
+ "people": "http://localhost:8000/api/1.0/people/"
+ }
+
+Tools like `curl` and libraries like `requests` can be used to build anything
+from small utilities to full-fledged clients targeting the REST API.
