| # Installation
 | ||
| The suggested and easiest way to install Homebrew is on the
 | ||
| [homepage](http://brew.sh).
 | ||
| 
 | ||
| The standard script installs Homebrew to `/usr/local` so that
 | ||
| [you don’t need sudo](FAQ.md#why-does-homebrew-say-sudo-is-bad-) when you `brew install`. It is a
 | ||
| careful script, it can be run even if you have stuff installed to
 | ||
| `/usr/local` already. It tells you exactly what it will do before it
 | ||
| does it too. And you have to confirm everything it will do before it
 | ||
| starts.
 | ||
| 
 | ||
| There are other ways to install Homebrew which provide you with more
 | ||
| flexibility. They are listed below the requirements.
 | ||
| 
 | ||
| ## Requirements
 | ||
| * An Intel CPU <sup>[1](#1)</sup>
 | ||
| * OS X 10.6 or higher <sup>[2](#2)</sup>
 | ||
| * Command Line Tools for Xcode: `xcode-select --install`,
 | ||
|   https://developer.apple.com/downloads or
 | ||
|   [Xcode](https://itunes.apple.com/us/app/xcode/id497799835) <sup>[3](#3)</sup>
 | ||
| * A Bourne-compatible shell for installation (e.g. bash or zsh) <sup>[4](#4)</sup>
 | ||
| 
 | ||
| If you want to build software that utilizes X11 components, you’ll need
 | ||
| to install [XQuartz](https://xquartz.macosforge.org). Apple provided a
 | ||
| distribution of XQuartz (“X11.app”) prior to OS X 10.8. This is
 | ||
| supported where possible, but many projects now require more up-to-date
 | ||
| libraries than those in the Apple distribution, so installing the
 | ||
| [latest version available for your
 | ||
| OS](https://xquartz.macosforge.org/trac/wiki/Releases) is recommended.
 | ||
| On 10.8 and newer, you should install the [most recent
 | ||
| version](https://xquartz.macosforge.org).
 | ||
| 
 | ||
| If you want to build Java bindings (in software such as Subversion,
 | ||
| Berkeley-DB, CMake, etc.) Apple’s “Java Developer Update” is required.
 | ||
| The latest versions are “Update 10” for 10.5 and “Update 9” for 10.6.
 | ||
| 
 | ||
| ## Alternative Installs
 | ||
| ### Untar anywhere
 | ||
| Just extract (or `git clone`) Homebrew wherever you want. Just
 | ||
| avoid:
 | ||
| 
 | ||
| * Directories with names that contain spaces. Homebrew itself can handle spaces, but many build scripts cannot.
 | ||
| * `/sw` and `/opt/local` because build scripts get confused when
 | ||
| Homebrew is there instead of Fink or MacPorts, respectively.
 | ||
| 
 | ||
| However do yourself a favor and install to `/usr/local`. Some things may
 | ||
| not build when installed elsewhere. One of the reasons Homebrew just
 | ||
| works relative to the competition is **because** we recommend installing
 | ||
| to `/usr/local`. *Pick another prefix at your peril!*
 | ||
| 
 | ||
| `mkdir homebrew && curl -L https://github.com/Homebrew/homebrew/tarball/master | tar xz --strip 1 -C homebrew`
 | ||
| 
 | ||
| ### Untar anywhere and then symlink the `brew` command elsewhere
 | ||
| You can also install Homebrew into e.g.
 | ||
| `~/Developer` and then symlink the brew command into `/usr/local/bin`.
 | ||
| 
 | ||
| Everything will install into `~/Developer`, but your
 | ||
| brew command is still in the path. **NOTE** that Homebrew will still
 | ||
| need to create symlinks into `/usr/local` or nothing will
 | ||
| work! But the actual files are installed to
 | ||
| `~/Developer/Cellar`.
 | ||
| 
 | ||
| ### Multiple installations
 | ||
| Create a Homebrew installation wherever you extract the tarball. Whichever brew command is called is where the packages will be installed. You can use this as you see fit, e.g. a system set of libs in `/usr/local` and tweaked formulae for development in `~/homebrew`.
 | ||
| 
 | ||
| ### Ignoring SSL certificate errors (not recommended)
 | ||
| The instructions on the homepage use `curl` to download a Ruby script
 | ||
| from GitHub over HTTPS. Older versions of OS X may not have the necessary CA
 | ||
| certificates to verify GitHub's SSL certificate. In that case, you can
 | ||
| add `--insecure` to the `curl` command, forcing `curl` to ignore SSL certificate errors.
 | ||
| This will leave your connection to GitHub vulnerable to MITM, and is <strong>not recommended</strong>.
 | ||
| You may consider updating your CA certificates instead.
 | ||
| 
 | ||
| ## Uninstallation
 | ||
| Uninstallation is documented in the [FAQ](FAQ.md).
 | ||
| 
 | ||
| <a name="1"><sup>1</sup></a> Not all formulae have CPU or OS requirements, but you can assume
 | ||
|     you will have trouble if you don’t conform. Also, you can find
 | ||
|     PowerPC and Tiger branches from other users in the fork network. See
 | ||
|     [Interesting Taps & Branches](Interesting-Taps-&-Branches.md).
 | ||
| 
 | ||
| <a name="2"><sup>2</sup></a> 10.7 or higher is recommended. 10.6 is supported on a
 | ||
|     best-effort basis. For 10.4 and 10.5, see [Tigerbrew](https://github.com/mistydemeo/tigerbrew).
 | ||
| 
 | ||
| <a name="3"><sup>3</sup></a> Most formulae require a compiler. A handful require a full Xcode
 | ||
|     installation. You can install Xcode, the CLT, or both; Homebrew
 | ||
|     supports all three configurations. Downloading Xcode may require an Apple Developer account on older versions of OS X. Sign up for free [here](https://developer.apple.com/register/index.action).
 | ||
| 
 | ||
| <a name="4"><sup>4</sup></a> The one-liner installation method found on
 | ||
|     [brew.sh](http://brew.sh) requires a Bourne-compatible shell (e.g.
 | ||
|     bash or zsh). Notably, fish, tcsh and csh will not work.
