+
+### Step 2: Configure Authentication
+
+When deploying the template, you’ll need to set up authentication for your Langtrace instance:
+
+- Under the **Configuration** section, add the following environment variables:
+  - `ADMIN_EMAIL`: Your desired admin email
+  - `ADMIN_PASSWORD`: Your desired admin password
+- For additional authentication methods (e.g. Google OAuth, Azure AD), refer to our [Authentication](/hosting/auth) guide to configure the necessary environment variables.
+

+
+### Step 3: Deploy the Template
+
+- Click **Deploy Stack** to start the deployment.
+- Northflank will automatically create and configure the required services — Clickhouse, PostgreSQL, and Langtrace Client.
+- Deployment typically takes about 2 minutes.

+
+Login using your previously configured admin credentials.  
+Then follow the [Quickstart Guide](/quickstart) to begin monitoring your LLM applications.
+
+## Cleanup
+
+To remove all resources:
+
+1. Go to your **Northflank project dashboard**.  
+2. Click on **Project Settings → Danger Zone → Delete Project**.  
+3. Confirm deletion to remove all services, addons, and configurations.
+
+## Troubleshooting
+
+<AccordionGroup>
+	<Accordion title="Clickhouse service keeps restarting or crashing">
+		This usually occurs when the Clickhouse service runs out of memory.
+		You can increase the memory limit of the Clickhouse service from the **Resources** tab under its configuration.
+	</Accordion>
+
+  <Accordion title="Cannot access public URL">
+		If the public URL doesn’t open, ensure the **langtrace-client** service has an **HTTP port (3000)** exposed and marked as **Public** under **Networking settings**.
+	</Accordion>
+</AccordionGroup>
