# Installation

In order to use Padrino, you need a few prerequisite libraries.

--------------------------------------------------------------------------------

## Ruby & RubyGems

First, you need to have a ruby interpreter installed. You can verify if you have
the interpreter installed by typing `which ruby` into the terminal and ensuring
a result. If not, we recommend installing [RVM](https://rvm.io/ "RVM") on most
platforms which manages your ruby interpreter installation and configuration.
Once RVM is installed, be sure to install Ruby 3.2 or newer (recommended,
minimum 2.7.8) or an alternative runtime such as
[JRuby](http://jruby.org/ "JRuby") according to your needs.

Once you have ruby, you need to make sure you have
[RubyGems](https://rubygems.org "RubyGems") which is the standard Ruby package
management method. You can ensure you have ruby gems by typing `gem -v` in the
terminal and ensuring a version result. If not, then be sure to
[download and install](https://rubygems.org/pages/download "download and
install") before continuing.

### Windows

A caveat: If you are on Windows, we recommend the
[RubyInstaller](http://rubyinstaller.org "RubyInstaller") project which takes
care of the above steps for you.

--------------------------------------------------------------------------------

## Padrino

Once you have ruby and rubygems installed properly, you just need to install the
Padrino framework with the `padrino` gem:

```shell
$ gem install padrino
```

This will install all the necessary padrino dependencies to get you started
creating applications. Now you are ready to use this gem to
[enhance your Sinatra projects](/guides/advanced-usage/standalone-usage-in-sinatra "enhance
your Sinatra projects") or to create new Padrino applications. If you are new to
Ruby or Sinatra, be sure to check out the
[Why Learn Padrino?](/guides/introduction/why-learn-padrino "Why Learn Padrino?") guide for more
information.

Inside a generated project, install its gems and its binstubs with
`bundle install && bundle binstubs --all` (or run each command with `bundle exec`), so that
`padrino` commands use the project's bundle.
