Getting married in Icmeler - help please!

Hello,
My friend is marrying her turkish boyfriend in August in Icmeler.
All their documentation has been taken care of in Turkey, but she is a bit lost about what she needs to obtain over here. Has anyone got any knowledge of what she needs to do/where she needs to go to sort documentation? The British embassy has no clear information on their website.
Thank you so much in advance!
