+## Setting up the server
+
+All data is stored in an SQLite3 database.
+
+The server and game rules are implemented in Javascript.
+The game state is stored in the database as a JSON blob.
+The server runs on Node with the Express.js and Socket.io frameworks.
+
+Redirect port 80 and 443 to 8080 and 80443:
+
+```
+sudo iptables -A PREROUTING -t nat -p tcp --dport 80 -j REDIRECT --to-ports 8080
+sudo iptables -A PREROUTING -t nat -p tcp --dport 443 -j REDIRECT --to-ports 8443
+```
+
+Create SSL certificate with Let's Encrypt certbot, or self-signed with OpenSSL:
+
+```
+openssl req -nodes -new -x509 -keyout key.pem -out cert.pem
+```
