+# Firebase Push Notifications
+
+To enable native push notifications (iOS/Android) for your self-hosted OneUptime instance, you need to configure Firebase Cloud Messaging (FCM). This allows OneUptime to send push notifications to mobile app users.
+
+## Prerequisites
+
+- Google account with access to [Firebase Console](https://console.firebase.google.com)
+- Access to your OneUptime server configuration
+- OneUptime mobile app installed on user devices
+
+## Setup Instructions
+
+### Step 1: Create a Firebase Project
+
+1. Go to the [Firebase Console](https://console.firebase.google.com)
+2. Click **"Create a project"** (or select an existing project)
+3. Enter a project name (e.g., "OneUptime Notifications")
+4. Follow the prompts to complete project creation
+
+### Step 2: Generate a Service Account Key
+
+1. In your Firebase project, go to **Project Settings** (gear icon in the top-left)
+2. Click the **"Service accounts"** tab
+3. Click **"Generate new private key"**
+4. Confirm by clicking **"Generate key"**
+5. A JSON file will be downloaded automatically — keep this file secure
+
+### Step 3: Extract Values from the JSON File
+
+Open the downloaded JSON file. You will need three values:
+
+```json
+{
+  "project_id": "your-project-id",
+  "client_email": "firebase-adminsdk-xxxxx@your-project-id.iam.gserviceaccount.com",
+  "private_key": "-----BEGIN RSA PRIVATE KEY-----\n...\n-----END RSA PRIVATE KEY-----\n"
+}
+```
+
+Map these to the OneUptime environment variables:
+
+| JSON Field | Environment Variable |
+|------------|---------------------|
+| `project_id` | `FIREBASE_PROJECT_ID` |
+| `client_email` | `FIREBASE_CLIENT_EMAIL` |
+| `private_key` | `FIREBASE_PRIVATE_KEY` |
+
+### Step 4: Configure OneUptime
+
+#### Docker Compose
+
+Add these environment variables to your `config.env` file:
+
+```bash
+FIREBASE_PROJECT_ID=your-project-id
+FIREBASE_CLIENT_EMAIL=firebase-adminsdk-xxxxx@your-project-id.iam.gserviceaccount.com
+FIREBASE_PRIVATE_KEY="-----BEGIN RSA PRIVATE KEY-----\n...\n-----END RSA PRIVATE KEY-----\n"
+```
+
+**Note:** The private key contains newlines. Wrap it in double quotes in your env file.
+
+#### Kubernetes with Helm
+
+Add these to your `values.yaml` file:
+
+```yaml
+firebase:
+  projectId: "your-project-id"
+  clientEmail: "firebase-adminsdk-xxxxx@your-project-id.iam.gserviceaccount.com"
+  privateKey: "-----BEGIN RSA PRIVATE KEY-----\n...\n-----END RSA PRIVATE KEY-----\n"
+```
+
+**Important:** Restart your OneUptime server after adding these environment variables so they take effect.
+
+## Environment Variables Reference
+
+| Variable | Description | Required |
+|----------|-------------|----------|
+| `FIREBASE_PROJECT_ID` | The Firebase project ID from the service account JSON | Yes |
+| `FIREBASE_CLIENT_EMAIL` | The service account email from the JSON file | Yes |
+| `FIREBASE_PRIVATE_KEY` | The RSA private key from the JSON file (contains newlines) | Yes |
+
+## Troubleshooting
+
+### Common Issues
+
+**Push notifications not being delivered:**
+- Verify all three environment variables are set correctly
+- Ensure the private key includes the `-----BEGIN RSA PRIVATE KEY-----` and `-----END RSA PRIVATE KEY-----` markers
+- Check that the service account has the necessary permissions in Firebase
+- Restart your OneUptime server after changing configuration
+
+**"Invalid credentials" error:**
+- Double-check that `FIREBASE_PROJECT_ID` matches the `project_id` in your JSON file
+- Verify `FIREBASE_CLIENT_EMAIL` matches the `client_email` exactly
+- Ensure the private key is properly quoted and newlines are preserved
+
+**"Service account not found" error:**
+- The service account may have been deleted in the Firebase Console
+- Generate a new service account key and update your configuration
+
+## Security Best Practices
+
+1. **Keep the service account key secure** — never commit it to version control
+2. **Limit service account permissions** — the default Firebase Admin SDK role is sufficient
+3. **Rotate keys periodically** — generate new service account keys and update your configuration
+4. **Monitor usage** — check the Firebase Console for unusual notification activity
+
