-Running the jobs in `run.py`:
+When you run `run.sh` it will create a transaction called `testing_sentry` in the Performance section of [sentry.io](https://sentry.io), and create a span for enqueing the job.

+It takes a couple of moments for the data to appear in [sentry.io](https://sentry.io).

+When you run a worker with `arq demo.WorkerSettings` it will create a transaction called `add_numbers` in the Performance section of [sentry.io](https://sentry.io), and will also create and issue in Sentry and connect it to the transaction.
