Here is some notes of my Raspberry Pi installation(Raspbian Wheezy).

Flattr is a social micropayments/microdonations provider. The basic idea is that: for a flattr user, you can transfer a small amount of money to your flattr account each month. Then when you’re browsing the web, you find some good content which is flattr supported and you want to sure your support, you can click the “flattr” button to do so. At the end of the month, all you “flattr-ed” content providers in this month will share the money in your flattr account. And of course the flattr website itself will get some money: as the content provider you get 90 percent and flattr.com keeps 10 percent.

In this post, I list the steps how I add flattr support to my Octopress blog.
