+% Nginx Configuration Generator
+
+nginx-confgen is a simple preprocessor and macro system for
+[nginx](http://nginx.org/) and nginx-like configuration files. It support
+variable substitution, macro expansion and using the output of arbitrary
+commands to generate config files.
+
+## Example
+
+```bash
+pre_set $certdir /etc/nginx-certificates/;
+
+# Fetch the 'resolver' from /etc/resolv.conf
+pre_exec $nameserver "grep nameserver /etc/resolv.conf \\
+                      | head -n 1 | sed 's/^nameserver //'";
+resolver $nameserver;
+
+# Convenient macro to create a HTTPS virtual host
+macro vhost $domain @aliases &block {
+  server {
+    listen [::]:443 ssl;
+    server_name $domain @aliases;
+
+    ssl_certificate     $certdir/$domain/fullchain.pem;
+    ssl_certificate_key $certdir/$domain/privkey.pem;
+    pre_if -f $certdir/$domain/ocsp.der {
+      ssl_stapling_file $certdir/$domain/ocsp.der;
+    }
+
+    █
+  }
+}
+
+vhost example.com www.example.com {
+  root /var/www/example.com;
+}
+```
