This is the first well-working version of frontsite, you can get the gem binary here, or get it installed by running gem install frontsite from your terminal, or, if you want to build it, download the source, go to its directory and run gem build to build it.
The recommended installation is to add it to your Gemfile, like gem 'frontsite' and then running the bundle command.
If you find a bug or have a good idea to work with, go and open an issue.
