-**Important point :**\\
-  - Select the VHost (website) mentioned along with the user and the port range.\\
-  - Enter the ‘App Web path’ . This would be like /app1 or /app2 or it can even be the website root i.e. /\\
-  - Enter the ‘App Port’ . The port entered under should be within the range of the port numbers mentioned in point 1.\\
-  - Select the ‘App Mode’. This should be ‘Development’\\
-With the above steps, you have mapped the web-server to the VHost/Website’s URL part and the port number where we can expect the NodeJS App to be running.
+**Important points :**\\
+  - Select the VHost (website) mentioned along with the user.\\
+  - Enter the ‘Local URL’ . This would be like /app1 or /app2 or it can even be the website root i.e. /\\
+  - Enter the ‘App Port’ . The port on which your App runs . You need to ensure that your App listens on interface 0.0.0.0 instead of 127.0.0.1 or localhost which typically are used\\
+  - The SSH daemon w.r.t. the concerned user will be restarted to enable backend port mappings. Therefore your dev mode app and any existing dev mode apps would need to be manually started. This applies whenever the SSH daemon is restarted. But when NodeJS Apps run in app/production mode, this does not apply. App/production mode is recommended when you have completed development or testing of the App, as each App in that mode has its own lifecycle.

 Now assuming that you created a app folder app1 , now under that folder upload all your source files including package.json . Lets’s say that we wish to user version 16 , to run NPM commands w.r.t. that ideally we will use npm16  .
