How do I set up Steem tipping on my website?

I have for the last week or so been building a site for my webcomic about Phill from GCHQ, and I have made profiles on Patreon and Flattr to keep the possibility to earn something on it. I have also put in a bitcoin address, and I thought that it would also be fine if people could tip some Steem or Steem-power (or Steem dollars for that matter). I have been trying to figure out which addresses to use for this, or which service... But to no avail.

I would be most appreciative if someone could give me a clue?
