how do i install composer locally on my pc?

You are welcome! If you are on PC, have you tried installing Wamp Server? From what I have read, is that the following might help.

Download and install Wamp http://www.wampserver.com/en/ For example the Wamp path (once installed) to php.exe would look like this C:\wamp\bin\php\php5.5.x\php.exe

At the php.5.5.x part of the path, you would put in the latest version of php installed. I believe the latest version included in Wampserver would be php.5.5.12

I already had XAMPP installed and this helped: http://www.codecheese.com/2015/02/installing-composer-xampp-windows/

I don't know if this works the same for MAMP, but I would think it would. If you don't have XAMPP installed you could try it with MAMP: https://teamtreehouse.com/library/setup-your-local-development-environment

You might want to try this link and scroll down to your operating system that you are installing it on https://getcomposer.org/doc/00-intro.md If you are on a PC, you can find a link to an EXE install file, or they give you instructions on setting it up manually. It mentions this about installing Composer with the EXE file : "This is the easiest way to get Composer set up on your machine. Download and run Composer-Setup.exe. It will install the latest Composer version and set up your PATH so that you can just call composer from any directory in your command line." There are separate instructions for Linux/Unix/OSX

yeah I found a similar program called xampp and figured how to install composer in it, I am currently working on the design I have and applying my new learned php knowledge :D thanks a bunch!

That is awesome! Good luck on your project design!
