## 📁 **Preparing the Files**

Before uploading your project, you must **exclude unnecessary files** to optimize the deployment.

#### ❌ **Files to Exclude**

Ensure the following files and directories are **not** included in your [`.zip`](/en/faq/general-questions/wip-how-to-compress.md):

```diff
- Gemfile.lock
- .git
- tmp/
- log/
```

📌 **Use a** [**`.discloudignore`**](/en/configurations/.discloudignore.md) **file** to automatically exclude these files.

🔗 **Need help setting up your** [**`Gemfile`**](/en/development-environment/supported-languages/ruby/gemfile.md) **or find** [**main file**](/en/faq/general-questions/what-is-the-main-file.md)**?**

Before deploying your website or API on Discloud, ensure that you meet the following **requirements**:

{% hint style="success" %}
[Platinum plan or higher](https://discloud.com/plans) is required to host websites or APIs.
{% endhint %}

{% hint style="success" %}
[A subdomain must be created](/en/faq/general-questions/how-to-create-a-subdomain.md) before deployment.
{% endhint %}

{% hint style="danger" %}

{% endhint %}

### ⚙️ Configuring Ruby on Rails

{% code title="config/application.rb" %}

```ruby
require_relative "boot"

require "rails/all"

# Requires the gems listed in the Gemfile, including those limited to :test, :development, or :production.
Bundler.require(*Rails.groups)

module RailsOnDiscloud
  class Application < Rails::Application
    # Initialize the default configuration for the originally generated Rails version.
    config.load_defaults 7.0
    # config.time_zone = "Central Time (US & Canada)"
    # config.eager_load_paths << Rails.root.join("extras")
    Rails.application.config.hosts = [
      IPAddr.new("0.0.0.0/0"),        # All IPv4 addresses.
      IPAddr.new("::/0"),             # All IPv6 addresses.
      "localhost",                    # Reserved domain localhost.
      "seusubdomínio.discloud.app"    # !!! Discloud Subdomain !!!
    ]
  end
end
```

{% endcode %}
