Installation

Installing Composer.

mhan@brahms:~/bin $ curl -sS https://getcomposer.org/installer | php
#!/usr/bin/env php
All settings correct for using Composer
Downloading...

Composer successfully installed to: /home/mhan/bin/composer.phar
Use it: php composer.phar

Make sure you have PHP (CLI version) installed. If you're the only developer on the machine, you may want to create a folder called ~/bin and put the generated composer file there. I usually rename mine to simply composer and then make it only user executable. By default it becomes other-executable. This way I can just invoke $ composer update from anywhere. Feel free to make it available to others by moving it to /usr/local/bin.

Notes

Be sure to run $ composer self-update often as there are numerous updates even during a day to this software, as of year 2015.
