 ```shell
 mkdir /home/dokku/myapp/nginx.conf.d/
-echo 'client_max_body_size 50M;' > /home/dokku/myapp/nginx.conf.d/upload.conf
+echo 'client_max_body_size 50m;' > /home/dokku/myapp/nginx.conf.d/upload.conf
 chown dokku:dokku /home/dokku/myapp/nginx.conf.d/upload.conf
 service nginx reload
 ```
 
 The example above uses additional configuration files directly on the Dokku host. Unlike the `nginx.conf.sigil` file, these additional files will not be copied over from your application repo, and thus need to be placed in the `/home/dokku/myapp/nginx.conf.d/` directory manually.
 
+For PHP Buildpack users, you will also need to provide a `Procfile` and an accompanying `nginx.conf` file to customize the nginx config *within* the container. The following are example contents for your `Procfile`
+
+    web: vendor/bin/heroku-php-nginx -C nginx.conf -i php.ini php/
+    
+Your `nginx.conf` file - not to be confused with Dokku's `nginx.conf.sigil` - would also need to be configured as shown in this example:
+
+    client_max_body_size 50m;
+    location / {
+        index index.php;
+        try_files $uri $uri/ /index.php$is_args$args;
+    }
+
+Please adjust the `Procfile` and `nginx.conf` file as appropriate.
