Plugins management is very important, as these plugins give us the capability to integrate different environments (which could be cloud platform) or on-premises resources with Jenkins, and also give us the capability to manage data on our resources like app servers, database servers, and so on.

In this panel, you will able to install, uninstall, and upgrade any specific plugins from the system. From the same panel, you can upgrade Jenkins as well.
