SomaFM XBMC Plugin moved! (See below)

The SomaFM Kodi plugin moved to a new repository: https://github.com/Soma-FM-Kodi-Add-On/plugin.audio.somafm

This description is a bit outdated. You can simply install this addon by browsing the official repositories from within Kodi.

Installation

Installation currently requires you to know where your addons folder is located. Please refer to the Kodi Wiki article on userdata to find it. To find the addons folder, simply replace every instance of userdata in the article with addons.

Git

Change into your addons folder
Clone the repository into a new folder plugin.audio.somafm
Done

On Linux and possibly Mac OSX

cd ~/kodi/addons/
git clone https://github.com/Oderik/xbmc-somafm.git plugin.audio.somafm

ZIP

Unfortunately, installing from a ZIP-file is not a lot easier

Download the ZIP Archive from GitHub
Extract the contents
Rename the resulting folder xbmc-somafm-master to plugin.audio.somafm
Move the folder to your addons folder

Again on Linux and possibly Mac OSX

wget --content-disposition https://github.com/Oderik/xbmc-somafm/archive/master.zip
unzip xbmc-somafm-master.zip 
mv xbmc-somafm-master/ plugin.audio.somafm
mv plugin.audio.somafm/ ~/kodi/addons/
