Residence permit in Turkey

It's that time again to extend the residence permit and as usual I get lost with the procedures and what is needed.
Fortunately a friend has just passed through the ordeal and has the info:

• Needed papers
• Wife must come along (that's what the text moving from right to left on that link means)
• You'll need to return one week after to pick up the permit

This is related to foreigners married to turkish citizens.
It seems to be the same process weather you do it for the first time or if you extend it.
I'll try to update this page with more information once I go through the process.

Update: more info here
