+# Zulip
+
+Zulip is an open-source team messaging platform with a unique topic-based threading model.
+
+## Dependencies
+
+- **SMTP** - For sending invitations and notifications
+- **Redis** - Used for caching and real-time event queuing
+
+Zulip bundles its own **PostgreSQL**, **RabbitMQ**, and **Memcached** instances — these are deployed alongside the main Zulip pod and are not shared with other apps.
+
+## Configuration
+
+Key settings in `config.yaml`:
+
+- **domain** - Where Zulip will be accessible
+- **adminEmail** - Admin account email (defaults to your operator email)
+- **smtp** - Email settings inherited from your Wild Cloud SMTP service
+
+## First-Time Setup
+
+1. Add and deploy the app:
+   ```bash
+   wild app add zulip
+   wild app deploy zulip
+   ```
+
+2. **First start takes 5–10 minutes** as Zulip runs hundreds of Django database migrations. Wait until the pod shows `1/1 Running`.
+
+3. The admin account is pre-configured with the `adminEmail` and `adminPassword` from `secrets.yaml`. Visit the app URL and log in.
+
+4. Complete the realm (organization) setup wizard on first login.
+
+## Inviting Users
+
+Send invitation emails from **Settings → Organization → Invitations**, or use pre-generated invite links.
+
+## Notes
+
+- The `secretKey`, `postgresPassword`, and `rabbitmqPassword` are all auto-generated in `secrets.yaml`
+- Zulip's topic-based threading keeps conversations organized — each stream (channel) has multiple topics
+- Mobile and desktop apps are available and connect to self-hosted instances
