 HTTP based tests
 ................
 
-see nettests/examples/example_httpt.py
+HTTP based tests will be a subclass of  `ooni.templates.httpt.HTTPTest`.
 
-TODO
+It provides methods `ooni.templates.httpt.HTTPTest.processResponseBody` and
+`ooni.templates.httpt.HTTPTest.processResponseHeaders` for interacting with the
+response body and headers respectively.
+
+For example, to implement a HTTP test that returns the sha256 hash of the
+response body (based on nettests/examples/example_httpt.py):
+
+::
+
+  from ooni.utils import log
+  from ooni.templates import httpt
+  from hashlib import sha256
+  
+  class SHA256HTTPBodyTest(httpt.HTTPTest):
+      name = "ChecksumHTTPBodyTest"
+      author = "Aaron Gibson"
+      version = 0.1
+  
+      inputFile = ['url file', 'f', None,
+              'List of URLS to perform GET requests to']
+      requiredOptions = ['url file']
+  
+      def test_http(self):
+          if self.input:
+              url = self.input
+              return self.doRequest(url)
+          else:
+              raise Exception("No input specified")
+  
+      def processResponseBody(self, body):
+          body_sha256sum = sha256(body).hexdigest()
+          self.report['checksum'] = body_sha256sum
+
+The report for this test looks like this:
