-   Basically, you need to run a server that would proxy the requests to
-   `/api/share`. to the Node.js server you started. Here's how to achieve this
-   in various HTTP servers:
+4. Set up a reverse proxy.
+
+   Basically, you need to run a reverse proxy that would redirect all incoming
+   requests to `localhost:3000`. Here's how to achieve this in various HTTP
+   servers:
 
    1. Apache
 
    ```apacheconf
-   DocumentRoot "<PATH_TO_SHARE2FEDI>/dist"
-
-   ProxyPass "/api/share"  "http://localhost:8080/"
+   ProxyPass "/" "http://localhost:3000/"
    ```
 
    2. Nginx
 
    ```nginxconf
-   root <PATH_TO_SHARE2FEDI>/dist;
-   index.html;
-
-   location /api/share {
-       proxy_pass http://localhost:8080/;
+   location / {
+       proxy_pass http://localhost:3000/;
    }
    ```
 
    3. Caddy
 
    ```caddy
-   root * <PATH_TO_SHARE2FEDI>/dist;
-   try_files index.html
-
-   handle_path /api/share {
-      reverse_proxy localhost:8080
-   }
+   reverse_proxy :3000
    ```
