M-xlist-packages brings up a buffer named Packages with a list of all packages. You can install or uninstall packages via this buffer. See Package Menu below.

The command C-hP (describe-package) prompts for the name of a package, and displays a help buffer describing the attributes of the package and the features that it implements.

By default, Emacs downloads packages from a package archive maintained by the Emacs developers and hosted by the GNU project. Optionally, you can also download packages from archives maintained by third parties. See Package Installation below.
