Answer 1

The "Getting Started" page is the introduction to the documentation. Most documentation will start off with installation instructions, just like Composer's do.

The page that contains information on the composer.json file is located here - under "Basic Usage", the second page.

I'd recommend reading over the documentation in full, so that you gain a better understanding of how to use Composer. I'd also recommend removing what you have and following the installation instructions provided in the documentation.

Answer 4

To install composer and add to your global path:

curl -sS https://getcomposer.org/installer | php
mv composer.phar /usr/local/bin/composer

run these in terminal. It does say if you get an error that usr doesn't exist, you do need to manually make it. I know an answer was selected, so this is for anyone who may see this in the future, as i am sometimes, and don't want to be advised to visit yet another site. Its simple just two lines, might have to be in sudo if you have permission error

Answer 5

Simple solution is install via this command :

curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/local/bin --filename=composer

To install package it's very simple :

 composer global require "phpunit/php-invoker=1.1.*"
