It’s easy to get started with VST plugins.
Typically, the process goes something like this:
Locate a VST plugin you want, and download it.
If the plugin is contained in aZIP file, unzip it.

If the VST comes with an executable file, run it.
This initiates an installation process that typically allows you to choose the installation folder for the VST.
Launch the DAW, and have it search for new VSTs.
