When you create a site with LocomotiveCMS, you do it locally first: this way you can focus on the design and the frontend code. That's what Wagon is used for: it initiates a site, runs a local http server, and eventually pushes your local code to a LocomotiveCMS engine.
Just in case you haven't yet, you need to install Wagon first.
1. Generate a site
A LocomoticeCMS site is stored in a local folder like any web project. We consider that you store your projects in
cd ~/workspace wagon init my_first_site -t bootstrap3
This will create a folder named my_first_site populated with a default index page and all the Twitter Bootstrap (version 3 here) resources.
Now you need to install a few gems:
cd my_first_site bundle install
2. Preview your site
bundle exec wagon serve
3. Edit your site
Your site can be edited with any text editor: Sublime Text 2, Textmate, vi, emacs, ...etc. There is no need to stop/start the serve command when you have modified a liquid template or content type.
