There are two different ways to get the extension installed: either directly from SVN (recommended) or via the prepackaged downloads.
Direct from SVN
TODO
Packaged Downloads
- Go to the Downloads Area and select a package appropriate to your platform (ZIP if you are unsure)
- Move the package into the vendor/extensions directory of your Radiant installation
- Unpack the download using an appropriate tool
- Move back to the root of your Radiant installation (make sure you are in a shell session)
- Run the following commands
- rake radiant:extensions:fckeditor:migrate
- rake radiant:extensions:fckeditor:update:public
- Start/Restart Radiant
I suppose, You try it in an exiting project. If so: copy the "fckeditor"-folder from "RADIANT_ROOT/public/javascripts/" into "YOUR_APP/public/javascripts/" and it should work. More informations You will also find here: http://github.com/djcp/radiant-fckeditor/tree/master.
