 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)
 
-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: 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
+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

+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
