+# Deploying n8n Community Edition
+
+Deploy n8n workflow automation on lttle.cloud in minutes using a pre-configured setup. If you prefer watching over reading, you can check out [this video guide](https://youtu.be/o0gm3xGiQSE) with the same steps.
+
+## Prerequisites
+
+- Active lttle.cloud account ([sign up for free](https://lttle.cloud/))
+- lttle CLI installed and configured ([Installation guide](./installing-the-cli.md))
+
+## Quick Deployment
+
+### 1. Download the configuration
+
+```bash
+curl -o n8n.yaml https://raw.githubusercontent.com/lttle-cloud/ignition/refs/heads/master/demos/n8n.yaml
+```
+
+### 2. Deploy to lttle.cloud
+
+```bash
+lttle deploy ./n8n.yaml
+```
+
+### 3. Monitor deployment status
+
+Wait for the machine to reach "ready" or "suspended" state:
+
+```bash
+lttle machine ls --ns n8n
+```
+
+Keep running this command until you see the status change to "ready" or "suspended".
+
+### 4. Get your n8n URL
+
+Once ready, get your public URL:
+
+```bash
+lttle query "'https://' + service('n8n-public', 'n8n').bind.external.host"
+```
+
+### 5. Access n8n
+
+Open the URL from step 4 in your browser and start building workflows!
+
+## What you get
+
+Your n8n instance includes:
+- **Persistent storage** - Workflows and data are preserved
+- **HTTPS encryption** - Secure access out of the box
+- **Auto-generated domain** - No DNS configuration needed
+- **Serverless** - Suspends when not in use to save costs. For more information, see [Machines > Mode](../resources/machines.mdx#mode).
+
+## Next steps
+
+Once n8n is running:
+- Create your first workflow
+- Connect to external services and APIs
+- Set up webhooks for automation
+- Explore n8n's extensive node library
+- Use a custom domain: Configure your own domain instead of the auto-generated one - see [Apps > Using custom domains](../resources/apps.mdx#using-custom-domains)
+
+## Troubleshooting
+
+**Cannot access the URL:**
+- Ensure the machine status is "ready" or "suspended"
+- Try the query command again to get the latest URL
+
+**Need to customize the setup:**
+- Download and modify the `n8n.yaml` configuration file
+- See [Apps configuration](../resources/apps.mdx) for available options
