+# This Computer
+
+Shows your IP address(es). Powered by a single static file and a Nginx config.
+
+Available at [this.computer](https://this.computer).
+
+## Make your own
+
+* Install Nginx, Certbot and Node.js (for the "build script").
+* Have a hostname for the website.
+* Have two hostnames for the IP checks, one with just an A record, one with just AAAA.
+
+Do this (substitute the hostnames):
+
+```bash
+
+# substitute the hostnames. $PWD/dist is where the html file is
+node build.js this.computer 4.this.computer 6.this.computer $PWD/dist
+
+# LetsEncrypt setup (skip and edit the main config if you prefer handling it yourself)
+
+# If target does not exist, try /etc/nginx/sites or /etc/nginx/conf.d 
+sudo mkdir -p /srv/tmp
+sudo cp conf/this-computer-certbot.conf /etc/nginx/sites-enabled
+sudo systemctl reload nginx
+sudo certbot certonly --webroot -w /srv/tmp -d this.computer -d 4.this.computer -d 6.this.computer
+# Assuming the above worked!
+echo 'systemctl reload nginx' | sudo tee /etc/letsencrypt/renewal-hooks/deploy/nginx.sh
+sudo chmod +x /etc/letsencrypt/renewal-hooks/deploy/nginx.sh
+
+# After certificates are ready:
+sudo cp conf/this-computer.conf /etc/nginx/sites-enabled
+sudo systemctl reload nginx
+
+```
