Rails: Trying to separate a model into an engine gem

Question

I'm new to here an to Rails so excuse any dumbness on my part.

I'm trying to do something really simple and can't seen to find a guide that's up to date and properly demonstrates how to do this.

I've written the app described in the official ruby on rails tutorial: http://edgeguides.rubyonrails.org/getting_started.html

Now I want to take one of the models, say Tags and make a gem out of that. How would I achieve this? I've read some on rails Engines but couldn't really figure out what goes where and mostly what the generators would look like.

I want to be able to write another app now, such as something flickr styled and by adding the new Tags gem to the Gemfile and having a

:has_many tags

In the picture model I've added a tags mechanism to all my pictures.

Any help would be greatly appreciated!
