Once you've done that, you'll use the `zulip-send` utility to notify you when certain events happen.

Here's some example code for sending a Zulip notification after a deployment has completed:

```bash
after 'deploy', 'notify:humbug'

namespace :notify do
  desc "Post a message to Zulip that we've deployed"
  task :humbug do
    # this will post to Zulip as the user defined in
    # ~/.zuliprc if you omit --user and --api-key
    run_locally "echo ':beers: I just deployed to #{stage}! :beers:' | zulip-send \
    --user capistrano-bot@example.com --api-key a0b1c2d3e4f5a6b7c8d9e0f1a2b3c4d5 \
    --site={{ external_api_uri_subdomain }} \
    --stream commits --subject deployments || true"
  end
end
```

Some notes:

*   If you prefer not to use `--user` and `--api-key` above, you can fill out `~/.zuliprc` on your Capistrano
machine. For instructions on how to write that file, see [the API page](/api).
*   You may need to change the `deploy` above to another step of your deployment process, if you'd like the
notification to fire at a different time.
