 1. Go to `/server/ssl`
 2. Execute `openssl req -newkey rsa:2048 -new -nodes -x509 -days 3650 -keyout key.pem -out cert.pem`
 
-
 ### Development
 
 ##### To start in development mode you must:
-1. Install the dependencies `npm install`.
-2. Run the `npm start:dev` command to start the server in dev mode.
-(Any change will trigger a refresh of the server)
 
+1. Install the dependencies `npm install`.
+
+2. Go to the `linx-devops/scaling-tools/private-system-truste-cert` project and generate a new server certificate and key:
+
+        sh create_certificate_for_domain.sh 192.168.1.110 #local IP
+        # generates files
+        nginx-selfsigned.crt
+        device.key
+
+3. You need to update the Video Server in the provisioning to point to your private IP. ex: https://192.168.1.199:3000
+
+4. The generated files must be moved to server/ssl and renamed as follows:
+
+        cp device.key  {mediasoup_project}/server/ssl/key.pem
+        cp nginx-selfsigned.crt {mediosup_project}/server/ssl/cert.pem
+
+5. Go to https://dev.linx.safemobile.com/dispatcher/resources/help/LINXHelp.html#safemobile-certificate-import and import the certificate for your system type
+
+6. The ANNOUNCED IP in .env must be configured to use the same private IP used in generating the certificate.
+
+7. Run the `npm start:dev` command to start the server in dev mode.
+   (Any change will trigger a refresh of the server)
 
 ### Production
 
 ##### To start in production mode you must:
 1. Install the dependencies `npm install`.
 2. Run the `npm start:prod` command to start the server in production mode.
-(To connect to the terminal, use `pm2 log video-server`)
+   (To connect to the terminal, use `pm2 log video-server`)
 
----
+
+### 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: 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
-assetType = asset type of the unit on which you are doing the test
+  ex: https://HOST/sfu/?assetId=1&&accountId=1&producer=true&dest_asset_id=75&assetName=Adi
+  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
