If you don’t check your admin panel very often when installing WordPress (perhaps because you prefer to use remote publishing) or want to make sure 
that your clients ‘ WordPress installations are updated, then this plugin is for you. You don’t need to regularly log in to your admin panel, 
subscribe to an RSS feed, or do anything other than install this plugin to receive notifications when WordPress updates, plugins, and themes are released to Telegram messenger.
All you have to do is install the telegram Update Notifier and forget about it until you get a message about the required updates.
To change the Update Notifier Telegram settings, go to the Update Notifier Telegram section in the main settings menu. From there, you can add a unique telegram ID
