+Using nginx as a proxy for Home Assistant allows you to serve Home Assistant securely over standard ports. This configuration file and instructions will walk you through setting up Home Assistant over a secure connection.
+
+### {% linkable_title 1. Get a domain name forwarded to your IP. %}
+
+Chances are, you have a dynamic IP Address (your ISP changes your address periodically). If this is true, you can use a Dynamic DNS service to obtain a domain and set it up to update with you IP. If you purchase your own domain name, you will be able to easily get a trusted SSL certificate later.
+
+
+### {% linkable_title 2 Install nginx on your server. %}
+
+This will vary depending on your OS. Check out Google for this. After installing, ensure that nginx is not running.
+
+### {% linkable_title 3. Obtain an SSL certificate. %}
+
+There are two ways of obtaining an SSL certificate.
+
+#### {% linkable_title Using Let's Encrypt %}
+If you purchased your own domain, you can use https://letsencrypt.org/ to obtain a free, publicly trusted SSL certificate. This will allow you to work with services like IFTTT. Download and install per the instructions online and get a certificate using the following command.
+
+```
+./letsencrypt-auto certonly --standalone -d example.com -d www.example.com
+```
+
+Instead of example.com, use your domain. You will need to renew this certificate every 90 days.
+
+#### {% linkable_title Using openssl %}
+
+If you do not own your own domain, you may generate a self-signed certificate. This will not work with IFTTT, but it will encrypt all of your Home Assistant traffic.
+
+```
+openssl req -x509 -newkey rsa:2048 -keyout key.pem -out cert.pem -days 9999
+sudo cp key.pem cert.pem /etc/nginx/ssl
+sudo chmod 600 /etc/nginx/ssl/key.pem /etc/nginx/ssl/cert.pem
+sudo chown root:root /etc/nginx/ssl/key.pem /etc/nginx/ssl/cert.pem
+```
+
+### {% linkable_title 4. Create dhparams file %}
+
+As a fair warning, this file will take a while to generate.
+
+```
+cd /etc/nginx/ssl
+sudo openssl dhparam -out dhparams.pem 2048
+```
+
+### {% linkable_title 5. Install configuration file in nginx. %}
+
+Create a new file `/etc/nginx/sites-available/hass` and copy the configuration file at the bottom of the page into it.
+
+### {% linkable_title 6. Enable the Home Assistant configuration. %}
+
+```
+cd /etc/nginx/sites-enabled
+sudo unlink default
+sudo ln ../sites-available/hass default
+```
+
+### {% linkable_title 7. Start NGINX. %}
+
+Double check this configuration to ensure all settings are correct and start nginx.
+
+
+### {% linkable_title 8. Port forwarding. %}
+
+Forward ports 443 and 80 to your server on your router. Do not forward port 8123.
+
+```

+    map $http_upgrade $connection_upgrade {
+        default upgrade;
