The "Resources" linked at the bottom of the page have lots more info.

Use

  $ git branch -r

to see remote branches.

Quick answer:

  $ git checkout -b release origin/release
  Branch release set up to track remote branch release from origin.

or for a new clone and git 1.6.5 or higher:

  $ git clone -b release git://cmake.org/cmake.git CMake

Informative answer:

  $ git branch
  * master
  $ git branch -r
    origin/HEAD -> origin/master
    origin/master
    origin/nightly
    origin/release
  $ git branch --track release origin/release
  Branch release set up to track remote branch release from origin.
  $ git checkout release

A "tracking" branch is just a local branch that has a couple
configuration entries:

  $ cat .git/config
  ...
  [branch "release"]
        remote = origin
        merge = refs/heads/release

You can read them with the "git config" command too:

  $ git config branch.release.remote
  origin
  $ git config branch.release.merge
  refs/heads/release
