Finding Android SDK on Mac and adding to PATH

I have installed Android Studio on my MacBook Air (OS Version 10.11 El Capitan) and have successfully written a small "hello, world" app and installed on device (Nexus 7) and ran on AVD. All I want to do now is be able to build the app and install it on device from the command line as opposed to Android Studio. I'm following the directions here:

and the relevant line is:

Make sure the Android SDK platform-tools/ directory is included in your PATH environment variable, then execute:

The problem is I can't find the Android SDK on my machine! I assume it's there because otherwise the program wouldn't compile and run through Android Studio? Perhaps that's a bad assumption? I'm new to Macs (I'm used to Windows) so I don't know the best way to search for the Android SDK. So my questions:

  1. How do I find Android SDK on my machine? Or prove to myself it's not there?
  2. If it's not there how do I install it?
  3. How do I change PATH to include Android SDK?
Solution
    1. How to find it

    You can see the location there – most of the time it is:

    /Users/<name>/Library/Android/sdk
    1. How to install it, if not there

    Standalone SDK download page

    1. How to add it to the path

    Open your Terminal edit your ~/.bash_profile file in nano by typing:

    nano ~/.bash_profile

    If you use Zsh, edit ~/.zshrc instead.

    Go to the end of the file and add the directory path to your $PATH:

    export PATH="${HOME}/Library/Android/sdk/tools:${HOME}/Library/Android/sdk/platform-tools:${PATH}"
