+Building and Testing with Responder
+===================================
+
+Responder comes with a first-class, well supported test client for your ASGI web services: **Requests**.
+
+Here, we'll go over the basics of setting up a proper Python package and adding testing to it.
+
+The Basics
+----------
+
+Your repository should look like this::
+
+    Pipfile   Pipfile.lock   api.py  test_api.py
+
+``$ cat api.py``::
+
+    import responder
+
+    api = responder.API()
+
+    @api.route("/")
+    def hello_world(req, resp):
+        resp.text = "hello, world!"
+
+    if __name__ == "__main__":
+        api.run()
+
+
+``$ cat Pipfile``::
+
+    [[source]]
+    url = "https://pypi.org/simple"
+    verify_ssl = true
+    name = "pypi"
+
+    [packages]
+    responder = "*"
+
+    [dev-packages]
+    pytest = "*"
+
+    [requires]
+    python_version = "3.7"
+
+    [pipenv]
+    allow_prereleases = true
+
+Writing Tests
+=============
+
+``$ cat test_api.py``::
+
+    import pytest
+    import api as service
+
+    @pytest.fixture
+    def api():
+        return service.api
+
+
+    def test_hello_world(api):
+        r = api.requests.get("/")
+        assert r.text = "hello, world!"
+
+``$ pytest``::

+(Optional) Proper Python Package
+--------------------------------
+
+Optionally, you can not rely on relative imports, and instead install your api as a proper package. This requires:
+
+1. A `proper setup.py <https://github.com/kennethreitz/setup.py>`_ file.
+2. ``$ pipenv install -e . --dev``
+
+This will ensure that your application gets installed in every developer's environment, using Pipenv.
