Installing Passenger is easy. During development, you use Bundler to install Passenger.

Open your application's Gemfile and add "passenger":

gem "passenger", ">= 5.3.2", require: "phusion_passenger/rack_handler"

Now open a terminal, go to your application's directory and run bundle install to install your gem bundle:

$ cd /path-to-your-app
$ bundle install
Installing passenger x.x.x
Your bundle is complete!

You can verify that it works by querying Passenger's version number:

$ bundle exec passenger --version
Phusion Passenger version X.X.X

"Phusion Passenger" is a trademark of Hongli Lai & Ninh Bui.
Installation in production is different, but we'll cover that later in the deployment tutorial.
