Improve configuration/setup documentation for better onboarding experience

[rjvitorino]

Description:

Improve the configuration/setup documentation to ensure that new users can easily and accurately set up the project.

Current Behaviour:

The current configuration/setup documentation is sparse and lacks detailed instructions, which may lead to confusion or errors during the setup process.

Expected Behaviour:

The setup documentation should include detailed, step-by-step instructions on how to configure and set up the project, namely the required environment variables and how to get them. This should cover all prerequisites, environment setup, installation steps, and configuration options. The goal is to make the setup process as smooth and error-free as possible for new users.

Examples:

1. Detailed instructions on setting up the development environment, including any necessary tools and dependencies.
2. Clear guidelines on how to configure environment variables and other configuration settings.
3. Step-by-step walkthrough of the installation process, including how to clone the repository, install dependencies, and run the application.
4. Troubleshooting section for common setup issues.

Describe alternatives you've considered:

1. Keeping the current documentation as is, but this may continue to cause confusion and setup errors.
2. Providing a video tutorial, but this may not be as accessible or easy to update as written documentation.

Additional Context:

Improving the setup documentation will enhance the onboarding experience for new contributors and users, reducing the time and effort required to get the project up and running.
