This question already has an answer here:

I inserted a two-pin header (P1) into this circuit using EasyEDA. Does the square outline mean that is the positive pin, or is there another meaning?

    \$\begingroup\$ Square pin is pin one, this has been asked on here before, so Elliot's link should show you what you need! \$\endgroup\$ – Hearth May 7 at 22:53

The square pin usually means it's pin 1. The polarity is up to you. Look at the 1x3 or other headers with more pins in the library, this will make more sense.
