# Ruby Getting Started


[Ruby ↗](https://www.ruby-lang.org/en/) is a dynamic, object-oriented programming language with a focus on simplicity and programmer happiness.

As said, there is no need for coding yet, we have created a [Github repository ↗](https://github.com/zerops-recipe-apps/ruby-hello-world-app), a **_recipe_**, containing a simple Ruby (Sinatra) web application served by Puma. The repo will be used as a source from which the app will be built.

1. Log in/sign up to [Zerops GUI ↗](https://app.zerops.io)

2. In the **Projects** box click on **Import a project** and paste in the following YAML config:

```yaml
project:
  name: recipe-ruby
  tags:
    - zerops-recipe

services:
  - hostname: app
    type: ubuntu/ruby@4.0
    zeropsSetup: prod
    enableSubdomainAccess: true
    buildFromGit: https://github.com/zerops-recipe-apps/ruby-hello-world-app

  - hostname: db
    type: postgresql@16
    mode: NON_HA
    priority: 1
```

3. Click on **Import project** and wait until all pipelines have finished.

**That's it, your application is now up and running! :star: Let's check it works:**

1. A _subdomain_ should have been enabled and visible in the project's **IP addressed & Public Routing Overview** box. Its format should look similar to this `https://app-808-8080.prg1.zerops.app`.
2. Click or the `subdomain` URL to open it in a browser and you should see

```
{"type":"ruby","greeting":"Hello from Zerops!","status":{"database":"OK"}}
```
