 ## Activate it
 
-* Edit your nginx config and add the following location to your main server block:
-```
-location /proxy {
-        return 404;
-}
-```
-
 * Set up a subdomain for the proxy with its nginx config on the same machine
-  *(the latter is not strictly required, but for simplicity we’ll assume so)*
+* Edit the nginx config for the upload/MediaProxy subdomain to point to the subdomain that has been set up
-* In this subdomain’s server block add
-```
-location /proxy {
-        proxy_cache akkoma_media_cache;
-        proxy_cache_lock on;
-        proxy_pass http://localhost:4000;
-}
-```
-Also add the following on top of the configuration, outside of the `server` block:
-```
-proxy_cache_path /tmp/akkoma-media-cache levels=1:2 keys_zone=akkoma_media_cache:10m max_size=10g inactive=720m use_temp_path=off;
-```
-If you came here from one of the installation guides, take a look at the example configuration `/installation/nginx/akkoma.nginx`, where this part is already included.
-
 * Append the following to your `prod.secret.exs` or `dev.secret.exs` (depends on which mode your instance is running):
-```
+```elixir
+# Replace media.example.td with the subdomain you set up earlier
 config :pleroma, :media_proxy,
       enabled: true,
       proxy_opts: [
             redirect_on_failure: true
       ],
-      base_url: "https://cache.akkoma.social"
+      base_url: "https://media.example.tld"
 ```
 You **really** should use a subdomain to serve proxied files; while we will fix bugs resulting from this, serving arbitrary remote content on your main domain namespace is a significant attack surface.
