 The [IDTA Asset Interface Description (AID) working group](https://github.com/admin-shell-io/submodel-templates/tree/main/development/Asset%20Interface%20Description/1/0) defines a submodel that can be used to describe the asset's service interface or asset's related service interfaces. The current AID working assumptions reuse existing definitions from [WoT Thing Descriptions](https://www.w3.org/TR/wot-thing-description11/) and hence it is possible to consume AAS with AID definitions with node-wot (e.g., read/subscribe live data of the asset and/or associated service).
 
-### Sample Application
-
-The file `AID_v03_counter.json` describes the counter sample in AID format. The `AssetInterfaceDescriptionUtil` utility class allows to transform the AID format to a valid WoT TD format which in the end can be properly consumed by node-wot.
+### Sample Applications
 
 #### Prerequisites
 
 -   `npm install @node-wot/td-tools`
 -   `npm install @node-wot/core`
 -   `npm install @node-wot/binding-http`
 
-#### Sample Code
+#### AAS/AID to WoT TD
+
+The file `counterHTTP.json` describes the counter sample in AID format for http binding. The `AssetInterfaceDescriptionUtil` utility class allows to transform the AID format to a valid WoT TD format which in the end can be properly consumed by node-wot.
 
 The example tries to load an AID file in AID format and transforms it to a regular WoT TD.
 
 ```js
-// aid-client.js
+// aid-to-td.js
 const fs = require("fs/promises"); // to read JSON file in AID format
 
 Servient = require("@node-wot/core").Servient;
