This seems like it has a good tutorial on getting involved in their ICO: https://steemit.com/steemit/@capital/overview-of-eos-and-instructions-for-its-upcoming-ico
If you can't grasp it's tech I probably wouldn't invest in the ico unless you are just backing it because of the team involved.
It's ironic that the tech that frees us from having to trust 3rd parties just means we have to trust the tech (especially if you're a non-tech person).
