+## Database migrations and asset precompilation

+In order for the `--no-migrations` and `--no-asset-precompilation` flags to work correctly, you need to use this configuration in your `Capfile`:
+
+```rb
+require 'capistrano/rails/assets' if ::ENV['NO_ASSET_PRECOMPILATION'].nil?
+require 'capistrano/rails/migrations' if ::ENV['NO_MIGRATIONS'].nil?
+```

 ## Development
 
 After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake test` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.
