Task: Integrate New Readme Into Project

Pull request overview

Updates the repository’s top-level readme to a more structured “project overview + setup” document, replacing the prior Spanish note about expired/out-of-stock product visibility.

Changes:

• Replaced the existing readme content with a Markdown-structured overview, features list, and contribution notes.
• Added setup instructions and best-practices bullets.

The stated PHP requirement "PHP 5.3 or higher" is inaccurate for this codebase: it uses the deprecated mysql_* extension (removed in PHP 7.0) and legacy ereg_* calls (also removed in PHP 7.0). Either constrain the supported PHP version range (e.g., PHP 5.x / <=5.6) or update the codebase to mysqli/PDO + preg_* and then document the newer minimum version.

Suggested change

	2. **Environment Setup**: Ensure you have PHP 5.3 or higher installed.
	3. **Run the Project**: Place the project in your server's root directory and start the server.
	2. **Environment Setup**: Ensure you have PHP 5.3 through PHP 5.6 installed. This codebase uses legacy PHP APIs that are not supported on PHP 7.0 or higher.
	3. **Run the Project**: Place the project in your server's root directory and start the server using a compatible PHP 5.x environment.

Setup instructions are incomplete: the app expects includes/config.php + DB tables (see install/update.php and includes/settings.php), so users typically need to run the /install flow or at least configure includes/config.php and create the schema. Please add those steps so a fresh clone can be brought up reliably.

Suggested change

	2. **Environment Setup**: Ensure you have PHP 5.3 or higher installed.
	3. **Run the Project**: Place the project in your server's root directory and start the server.
	2. **Environment Setup**: Ensure you have PHP 5.3 or higher installed, along with a MySQL-compatible database.
	3. **Deploy the Project**: Place the project in your web server's root directory or another served location.
	4. **Configure the Application**: Create and configure `includes/config.php` with the correct database connection and application settings required by your environment.
	5. **Create the Database**: Create an empty database for the application before running it for the first time.
	6. **Initialize the Schema**: Open the `/install` flow in your browser and complete the installer so the required tables are created/updated. If your deployment uses the updater directly, ensure the schema expected by `install/update.php` and `includes/settings.php` is applied before using the app.
	7. **Run the Project**: After configuration and installation are complete, start the server and load the application.

"Follow the [code_style] conventions" appears to be a placeholder/broken reference (no code_style doc/link exists in the repo). Please replace it with an actual link/path to the project's style guidelines or remove the bullet to avoid confusing contributors.

Suggested change

	- Follow the [code_style] conventions.
	- Follow the existing code style conventions used throughout the project.

This file is readme.txt but the new content is written as Markdown (e.g., ###, **bold**, numbered lists). If the intent is for GitHub to render formatting, consider renaming to README.md; otherwise convert to plain text so the headings/lists display cleanly in a .txt viewer.

	### Project Overview
	This project is focused on managing product availability and ensuring that expired or out-of-stock items are not displayed or available for purchase. The implementation of these functionalities affects the following areas:
	1. **Index**: The homepage where products are initially displayed.
	2. **Search**: The search functionality used to find products.
	3. **Categories**: The display of products sorted by categories.
	### Key Features
	- **Product Availability**: Products that have expired or are out-of-stock will not be shown.
	- **Purchase Restriction**: Items that are displayed but are unavailable cannot be purchased.
	### Setup Instructions
	1. **Clone the Repository**: Use `git clone` to get a copy of the project.
	2. **Environment Setup**: Ensure you have PHP 5.3 or higher installed.
	3. **Run the Project**: Place the project in your server's root directory and start the server.
	### Best Practices
	- Follow the [code_style] conventions.
	- Ensure any changes conform to existing patterns and naming conventions.
	### Contributing
	- Please submit issues and pull requests for any improvements or fixes.
