+### 2.10 install_middleware
+
+When using WOVN.rb in a Rails environment, this parameter controls whether the WOVN.rb middleware will be automatically installed or not.
+
+By default, WOVN.rb is automatically installed as the first middleware.
+If you are using Rack::Deflater or other middleware that needs to be executed first, set this parameter to `false` and manually insert the middleware appropriately.
+WOVN.rb needs to be added after any compression middleware.
+
+```ruby
+  config.middleware.use Rack::Deflater
+  config.middleware.insert_after Rack::Deflater, Wovnrb::Interceptor
+
+  config.wovnrb = {
+    :project_token => 'EnS!t3',
+    :default_lang => 'en',
+    :supported_langs => ['en'],
+    :url_pattern => 'path',
+    :install_middleware => false
+  }
