+#### Add support for custom error pages

+```bash
+$ cp -rp ./error_pages.conf /etc/nginx/snippets/
+$ cp -rp ./error_pages_content.conf /etc/nginx/snippets/

+
+```
+server {
+
+## Nginx Maintenance Mode
+include snippets/maintenance-page.conf;
+## Custom Error Pages
+include snippets/error_pages.conf;
+
+}
+```
+
+## Scheduled maintenance
+
+Example shell script:
+
+Name the script, someting like: ```pg_backup_cron.sh```
+
+```bash
+#!/usr/bin/env bash
+
+# Turn on maintenance mode
+/path/to/Nginx-Maintenance-Mode/maintenance.sh hostname.com on
+# Run database backups
+/path/to/pgbackup/pg_backup.sh
+# Turn off maintenance mode
+/path/to/Nginx-Maintenance-Mode/maintenance.sh hostname.com off
+exit 0
+```
+
+Add job to cron:
+
+```
+$ crontab -e
+```
+```
+@daily bash /path/to/pgbackup/pg_backup_cron.sh > /dev/null 2>&1 #Automated PostgreSQL Backup on Linux
+```
+
+Used in this example: [pgbackup - Automated PostgreSQL Backup on Linux](https://github.com/tmiland/pgbackup)
+
+## Why maintenance mode is important
+
+- Helps your SEO rankings
+
+As [recommended by Google](https://webmasters.googleblog.com/2011/01/how-to-deal-with-planned-site-downtime.html), Maintenace Mode is using the 503 service unavailable result code, which tells search engine crawlers that the downtime is temporary.
