+Assuming you have a [local version of PostHog](https://posthog.com/docs/developing-locally) running, you can run `python3 example.py` to see the library in action.
+
+## Running the Django Sentry Integration Locally
+
+There's a sample Django project included, called `sentry_django_example`, which explains how to use PostHog with Sentry.
+
+There's 2 places of importance (Changes required are all marked with TODO in the sample project directory)
+
+1. Settings.py
+    1. Input your Sentry DSN
+    2. Input your Sentry Org and ProjectID details into `PosthogIntegration()`
+    3. Add `POSTHOG_DJANGO` to settings.py. This allows the `PosthogDistinctIdMiddleware` to get the distinct_ids
+
+2. urls.py
+    1. This includes the `sentry-debug/` endpoint, which generates an exception
+
+To run things: `make django_example`. This installs the posthog-python library with the sentry-sdk add-on, and then runs the django app.
+Also start the PostHog app locally.
+Then navigate to `http://127.0.0.1:8080/sentry-debug/` and you should get an event in both Sentry and PostHog, with links to each other.
