You're looking for a simple "Hello, World!" program in Ruby!

Here it is:

puts "Hello, World!"

This will print "Hello, World!" to the console.

If you want to create a Ruby file and run it, you can do the following:

Create a new file called hello.rb (or any other name you like, but with a .rb extension).
Open the file in a text editor and add the following code:
```
puts "Hello, World!"
```
Save the file.
Open a terminal or command prompt and navigate to the directory where you saved the file.
Run the file using the ruby command: ruby hello.rb

This will print "Hello, World!" to the console.

That's it! You've just written and run your first Ruby program.
