hello @hiorws

thank you for reminding about license. Expressions of Peace, are human rights to experience, yet exist with the utmost motivation to, maybe ironically but found necessarily, create/incentivize, Peace Industries as well.
For all that, we'll be using Creative Commons license, with a BY-SA type.

For now, included a link to license on the footer part of App.js, will add a LICENSE.md to repository this month.

here's the commit relating to license:
