State System Requirements

[ravage84]

Though it will be enforced through Composer, it would be better to clearly state the system requirements.

What OSes are generally supported? I Assume at least:

• Windows
• Linux

What PHP versions are supported?
According to https://github.com/povils/phpmnd/blob/v1.0.3/composer.json#L21 it would be PHP 5.6.+ incl. 7.x, right now.

Are there any PHP extensions needed? It seems not, at the moment.

These requirements should live where the installation is explained. See #19.

It needs the System requirement section in README.

And we can refer the require block in composer.json to complete this section.

Agreed.

I wouldn't do it that way. Even though writing a human readable list foces you to keep it synced, it's much more developer friendly than to force people to interpret the composer controlled requirements.
