title: Homebrew changing prefix
body: <p>Is there a way to prefix on my homebrew?
  When I type <code>brew --prefix</code>
  it shows /Users/username/homebrew ..</p>
  <p>I was installing via git clone way:</p>
  <pre><code>git clone https://github.com/Homebrew/brew homebrew
  eval &quot;$(homebrew/bin/brew shellenv)&quot;
  brew update --force --quiet
  chmod -R go-w &quot;$(brew --prefix)/share/zsh&quot;
  </code></pre>
