+### Apache Reverse Proxy
+
+Add this to the site config file on your Apache server after you have changed the relevant parts in the <> brackets, and inserted the path to you certificates.
+For this to work you must enable at least the following mods using `a2enmod`:
+  - `ssl`
+  - `proxy_module`
+  - `proxy_wstunnel_module`
+  - `rewrite_module`
+
+```bash
+<IfModule mod_ssl.c>
+<VirtualHost *:443>
+    ServerName <sub>.<domain>.<tld>
+
+    ErrorLog ${APACHE_LOG_DIR}/error.log
+    CustomLog ${APACHE_LOG_DIR}/access.log combined
+
+    ProxyPreserveHost On
+    ProxyPass / http://localhost:<audiobookshelf_port>/
+    RewriteEngine on
+    RewriteCond %{HTTP:Upgrade} websocket [NC]
+    RewriteCond %{HTTP:Connection} upgrade [NC]
+    RewriteRule ^/?(.*) "ws://localhost:<audiobookshelf_port>/$1" [P,L]
+
+    # unless you're doing something special this should be generated by a
+    # tool like certbot by let's encrypt
+    SSLCertificateFile /path/to/cert/file
+    SSLCertificateKeyFile /path/to/key/file
+</VirtualHost>
+</IfModule>
+```
