There are two ways to execute drush-deploy from the command line.

The primary way is to run the drush-deploy command which is provided by the package. Using this you can easily deploy any Drupal project:
```
 drush-deploy TARGET=staging 
```
This will by default run the deploy task however you can override this by supplying an explicit list of tasks to run:
```
 drush-deploy deploy:setup targets TARGET=staging
```
The drush-deploy command does not require any files in the Drupal project to run.
Because it is a capistrano plugin it also can be used like any capistrano plugin in a capistrano project. If your Drupal project has a capfile with
```
 require 'drush_deploy'
```
in it you can run the cap program supplied by capistrano. cap does not have a default task so to deploy you must specify it explicitly.
```
 cap deploy TARGET=staging
```

Deployment

When doing a deploy, drush-deploy will perform the following actions by default.

Create a new unique directory releases/<current timestamp> in the destination directory and upload the site files to it.
Symlink shared/default/files to releases/<current timestamp>/sites/default/files
Generate shared/default/settings.php from the default.settings.php file along with database settings. See Database-Configuration
Backup the current Drupal database as <db_name>_<previous release timestamp>
Run any update scripts of updated Drupal modules (See update-modules on Variables)).
Symlink releases/<current timestamp> to current, making it the live version of the site
