 ## Configuration
 ### Reverse Proxy
-Apache2 configuration to put under the relevant virtual domain:
+#### Apache2
+The specific configuration to put under the relevant `VirtualHost`:
 ```
-ProxyPreserveHost on
-ProxyPass /_matrix/identity/ http://mxisdInternalIpAddress:8090/_matrix/identity/
-ProxyPass /_matrix/client/r0/user_directory/ http://mxisdInternalIpAddress:8090/_matrix/client/r0/user_directory/
-ProxyPass /_matrix/ http://HomeserverInternalIpAddress:8008/_matrix/
+ProxyPass /_matrix/client/r0/user_directory/ http://0.0.0.0:8090/_matrix/client/r0/user_directory/
 ```
 `ProxyPreserveHost` or equivalent must be enabled to detect to which Homeserver mxisd should talk to when building
 results.
 
+Your `VirtualHost` should now look like this:
+```
+<VirtualHost *:443>
+    ServerName example.org
+    
+    ...
+    
+    ProxyPreserveHost on
+    ProxyPass /_matrix/client/r0/user_directory/ http://localhost:8090/_matrix/client/r0/user_directory/
+    ProxyPass /_matrix/identity/ http://localhost:8090/_matrix/identity/
+    ProxyPass /_matrix/ http://localhost:8008/_matrix/
+</VirtualHost>
+```
+
+#### nginx
+The specific configuration to add under your `server` section is:
+```
+location /_matrix/client/r0/user_directory {
+    proxy_pass http://0.0.0.0:8090/_matrix/client/r0/user_directory;
+    proxy_set_header Host $host;

+}

 ### DNS Overwrite
 Just like you need to configure a reverse proxy to send client requests to mxisd, you also need to configure mxisd with
 the internal IP of the Homeserver so it can talk to it directly to integrate its directory search.

 ### Synapse
 Add your mxisd domain into the `homeserver.yaml` at `trusted_third_party_id_servers` and restart synapse.
