-### Web client
+---
 
 - The server will start by default on port 3000, and the ssl certificates will have to be configured
 - The web client can be accessed using the /sfu path
-ex: https://HOST/sfu/?assetId=1&&accountId=1&producer=true&dest_asset_id=75&assetName=Adi
+ex: http://localhost:3000/sfu/?assetId=1&&accountId=1&producer=true&assetName=Adi&assetType=linx
 assetId = asset id of the unit on which you are doing the test
 accountId = account id of the unit on which you are doing the test
 producer = it will always be true because you are the producer
 (it's possible to put false, but then you have to have another client with producer true)
 assetName = asset name of the unit on which you are doing the test
-dest_asset_id= the addressee with whom the call is made
-- To make a call using this client, you need a microphone and permission to use it
-- For any changes related to the client, the command `npm run watch' will have to be used to generate the bundle.js used by the web client
+assetType = asset type of the unit on which you are doing the test
