I’m not familiar with capistrano at all, I kind of use it in daily base but what I’m capable of is just the one major command: ca deploy, heh that’s all I got.

Capistrano Callback Order

If you like me always get confused by the callback orders, image is really gonna help you out.

Capistrano Task explanation

Capistrano recipes: deploy is brief explanations of each task, same in the source code I think, highly recommend you go through them once.

Another good resource is capistrano recipes source code

task :update do
  transaction do

Like this :update task is easy to guess: run update_code and create_symlink in a transaction.
