You can add the xbmc repository to your XBMC:
http://xbmc.flirc.tv
Alternatively, to install without leaving the XBMC environment, select 'File Manager' from the XBMC System Drop-Down Menu, then double-click 'Add Source' and enter:
http://xbmc.flirc.tv
as the path. You will then be able to install the plugin directly from the 'Install from zip file' on the Add-ons menu by selecting the source you have just created.
If using linux, see "Linux Requirements"
Linux users need a udev rule in order for the XBMC plugin to be able to open flirc.
Copy the file in the linux directory, 51-flirc.rules into etc/udev/rules.d/
You must be the root user in order to do this.
