To get a free website and build it using Odoo, you can follow these steps:

• Sign up for a free Odoo account: Visit the Odoo website (https://www.odoo.com/) and create a free account. This will give you access to the Odoo platform and its website builder.

• Set up your Odoo instance: Once you have created an account, you will be guided to set up your Odoo instance. Follow the instructions provided to complete the setup process.

• Access the Website Builder: After setting up your Odoo instance, log in to your account. From the dashboard, click on the "Website" tab or navigate to the website builder.

• Choose a website template: Odoo provides a range of website templates to choose from. Browse the available options and select a template that suits your needs and preferences.

• Customize your website: Once you have selected a template, you can start customizing your website. Use the built-in drag-and-drop editor to modify the layout, add sections, change colors, upload images, and personalize the content.

• Add website functionality: Odoo allows you to integrate various functionalities into your website, such as contact forms, blogs, e-commerce features, and more. Explore the available modules and add the desired features to enhance your website's functionality.

• Configure website settings: Adjust the general settings of your website, such as the site title, meta description, navigation menus, and SEO settings. These settings help optimize your website for search engines and improve its visibility.

• Publish your website: Once you are satisfied with the design and content of your website, it's time to publish it. Click on the "Publish" or "Go Live" button to make your website accessible to the public.

• Customize your domain (optional): By default, your website will have a subdomain provided by Odoo. If you want to use a custom domain (e.g., www.yourdomain.com), you can either purchase a domain from a domain registrar or use an existing one you already own. Follow Odoo's instructions to configure your custom domain and link it to your website.

Remember, while the basic Odoo website builder is free, certain advanced features and modules may require a paid subscription or additional fees. Make sure to review the pricing details on the Odoo website if you plan to use any premium features.

Additionally, if you need more control and flexibility over your website, you might consider using self-hosted Odoo Community Edition or deploying Odoo on a hosting provider that supports Odoo installations. However, these options involve more technical complexity and might require server management knowledge.
