Explains how to install Arcanist on Mac OS X.

= Required Components =

You need to install:

  - PHP, which should be installed by default.
  - Arcanist itself, see @{article:Arcanist User Guide}.
  - SVN, Git, or Mercurial.

Then, configure:

  - Your PATH environmental variable should include `arcanist/bin`, and
    `php` and your VCS command (`svn`, `hg`, `git`) should be in PATH. When you
    type `php`, `arc`, or (for example) `git` from the command line, they should
    all do something.
  - Your EDITOR environmental variable should point at some valid CLI editor,
    like `nano`, which is the best editor.

You can edit your `~/.profile` to permanently configure environmental variables.

Now you should be able to run `arc` like a normal command.
