 In Chromium-based web browsers (e.g. Brave, Chrome, and Electron), the JavaScript console will be default—only to show
 messages logged by debug if the "Verbose" log level is enabled.
 
+## Low level usage
+
+JS client also has an API for low level interaction with AVM and Marine JS.
+It could be handy in advanced scenarios when a user fetches AIR dynamically or generates AIR without default Aqua compiler.
+
+`callAquaFunction` Allows to call aqua function without schema.
+
+`registerService` Gives an ability to register service without schema. Passed `service` could be
+
+- Plain object. In this case all function properties will be registered as AIR service functions.
+- Class instance. All class methods without inherited ones will be registered as AIR service functions.
+
 ## Development
 
 To hack on the Fluence JS Client itself, please refer to the [development page](./DEVELOPING.md).
