+### Configuring servers
+
+Typical deployment of multiple languages serve each language from a different subdirectory.
+Users are redirected to the preferred language defined in the browser using the
+`Accept-Language` HTTP header. If the user has not defined a preferred language,
+or if the preferred language is not available, then the server falls back to the default language.
+Users can change the language by navigating to other subdirectories, which often occurs using a
+menu implemented in the application.

+#### Nginx
+
+The following is an example of an Nginx configuration.
+
+```
+http {
+
+    # Browser preferred language detection (does NOT require AcceptLanguageModule)
+    map $http_accept_language $accept_language {
+        ~*^de de;
+        ~*^fr fr;
+        ~*^en en;
+    }
+    # ...
+}
+
+server {
+    listen 80;
+    server_name localhost;
+    root /www/data;
+
+    # Fallback to default language if no preference defined by browser 
+    if ($accept_language ~ "^$") {
+        set $accept_language "fr";
+    }
+
+    # Redirect "/" to Angular app in browser's preferred language
+    rewrite ^/$ /$accept_language permanent;
+
+    # Everything under the Angular app is always redirected to Angular in the correct language
+    location ~ ^/(fr|de|en) {
+        try_files $uri /$1/index.html?$args;
+    }
+    # ...
+}
+```
+
+#### Apache
+
+The following is an example of an Apache configuration.
+
+```
+<VirtualHost *:80>
+    ServerName localhost
+    DocumentRoot /www/data
+    <Directory "/www/data">
+        RewriteEngine on
+        RewriteBase /
+        RewriteRule ^../index\.html$ - [L]
+
+        RewriteCond %{REQUEST_FILENAME} !-f
+        RewriteCond %{REQUEST_FILENAME} !-d
+        RewriteRule (..) $1/index.html [L]
+
+        RewriteCond %{HTTP:Accept-Language} ^de [NC]
+        RewriteRule ^$ /de/ [R]
+
+        RewriteCond %{HTTP:Accept-Language} ^en [NC]
+        RewriteRule ^$ /en/ [R]
+
+        RewriteCond %{HTTP:Accept-Language} !^en [NC]
+        RewriteCond %{HTTP:Accept-Language} !^de [NC]
+        RewriteRule ^$ /fr/ [R]
+    </Directory>
+</VirtualHost>
+```
