I don‘t really get how to donate at all. Is it just my upvote? I tried clicking on „Donate“ on the banner but it‘s just a picture. The description of account creation, scouts and quests is fine, curious to try that. But how to buy 1 Clean Token for 0.1 steem I don‘t know.

It's as simple as a transfer to Steem.
You send your donation as a "steem" to @cleanplanet and you will receive Clean Tokens on your Steem-Engine Account.

There will be an article on this this weekend to talk about it!
