 #### Custom web pages
 
-If you want to include other pages,
+You can skip uploading a web page
-they need their separate nginx config
+by setting `www_folder=disabled` in `chatmail.ini`.
-under `/etc/nginx/sites-enabled/`.
-Note that they need to listen on port 8443 instead of 443.
 
-To request TLS certificates for the corresponding domains,
+If you want to manage your web pages outside this git repository,
-point the DNS records to your Server and run `acmetool want <domain>`.
+you can set `www_folder` in `chatmail.ini` to a custom directory on your computer.
-You can find the TLS certificates under `/var/lib/acme/live`.
+`cmdeploy run` will upload it as the server's home page,
-They will be automatically renewed.
+and if it contains a `src/index.md` file,
+will build it with hugo.
