+This allows for an integration between Django testing, which utilizes unittest and Gradescope's JSONTestRunner to obtain the JSON output of the Django test cases.

 To enable this, complete the following steps:  
 
-First, in your settings.py, insert the line:
-```
-`TEST_RUNNER = 'gradescope_utils.autograder_utils.gradescope_django_runner.GradescopeDjangoRunner'`
+* The `GRADESCOPE_PARAMETERS` is used to set different arguments for the JSONTestRunner from the default ones. In your settings.py, insert the lines below: 
+```python
+import sys
+
+TEST_RUNNER = 'gradescope_utils.autograder_utils.gradescope_django_runner.GradescopeDjangoRunner'
+
+GRADESCOPE_PARAMETERS = {
+    'stream': sys.stdout,
+    'descriptions': True,
+    'verbosity': 1,
+    'failfast': False,
+    'buffer': True,
+    'visibility': "visible",
+    'stdout_visibility': None,
+    'post_processor': None,
+    'failure_prefix': "Test Failed: "
+}
 ```
 
-Then, within your `run_autograder`, run the following command:
+* You can either pass a file descriptor to `/autograder/results/results.json` as an argument to `'stream'` in the `GRADESCOPE_PARAMETERS`. Alternatively, within your `run_autograder`, run the following command:
 ```
 python3 manage.py test -v 0 > /autograder/results/results.json
-```
