## How to deploy a $brandName project with zero downtime?
- First, [install](/docs/installation.md) the Deployer.
- Second, require `$recipe->recipePath` recipe into your _deploy.php_ or _deploy.yaml_ file.
- Third, $now you can have a zero downtime deployment!
Did you know that you can deploy **$brandName** project with a single command? $justRun `dep deploy`.
Something went wrong? Just run `dep rollback` to rollback your changes.
Also, you can take an $advantage of the [Deployer's CLI](/docs/cli.md) to deploy your project.
$another feature of the Deployer is [provisioning](/docs/recipe/provision.md). Take any server, and run `dep provision` command.
This command will configure webserver, databases, php, $https, and more.
You will get everything you need to run your **$brandName** $application.
