To start using iMatrix on your iPhone you need to make three steps:

Install iMatrix application

This is required step. To install iMatrix:

• Add new source to Installer.app: http://www.iMatrix.LT/repo/repository.plist and refresh sources
• Staying in Installer.app, go to Install tab, find '2D Codes' section and install iMatrix from there as usual
• Leave Installer and find iMatrix icon on your desktop (summer board)

Register

• Then, go to this site and create your personal account. Please note, that you do not need to validate your account by valid e-mail, credit card number or any other means. You have to register because it is the only way to separate your codes from others. Each time you login, you have access to previuosly created codes.
• After registration on this site, launch iMatrix on your phone; go to Preferences and press 'Register' button. You will be redirected to special page on this site (via Safari) where you have to login
• Then, return to iMatrix and press Sync button (or shoot codes you have created). This binds iMatrix on your iPhone to your account on site. That is all!

Create codes

Start using iMatrix by creating codes under My Account/New code section.
