Introduction
============

This documentation provides an overview of our OpenAPI implementation, including features, architecture placement, and guides for users and developers. 
The OpenAPI specification is a powerful framework for **defining and interacting with RESTful APIs**.
In this document, we will cover everything you need to know **to use and contribute** to our OpenAPI project, as well as guide you on how to create your own OpenAPI specifications for your APIs.

Features
========

- **Comprehensive API Documentation**: Automatically generated, easy-to-read API documentation.
- **Standardized Interface**: Follows the OpenAPI Specification to ensure consistency and compatibility.
- **Interactive API Explorer**: Test API endpoints directly from the documentation.
- **Client SDK Generation**: Generate client libraries in various programming languages.
- **Validation and Testing Tools**: Includes tools for validating and testing API requests and responses.

Place in Architecture
=====================
Our aerOS OpenAPI implementation defines the APIs to be exposed. It is integrated into our architecture to ensure standardized API definitions and seamless communication. Here is a simplified view of its place in our architecture:

User Guide
==========

This section will help users understand how to use the APIs defined by our OpenAPI specification, how to create them ad how to generate code. 

Prerequisites
-------------

- Basic understanding of RESTful APIs and HTTP methods.
- An active internet connection.
- Access to our API documentation and a valid API key (if required).

Installation
-------------

To use OpenAPI, no installation is required. It is possible to use the `Swagger Editor <https://editor.swagger.io/>`__ to create the documentation, clients, server. etc.
To use OpenAPI locally, it is recommended to use the `OpenAPI extension <https://marketplace.visualstudio.com/items?itemName=42Crunch.vscode-openapi>`__ for Visual Code.

Configuration Options
---------------------

Our OpenAPI supports various configuration options to customize your API interaction:

- **Authentication**: Configure API keys or OAuth tokens.
- **Request Headers**: Customize headers for specific requests.
- **Query Parameters**: Use query parameters to filter and customize responses.
- **Error Handling**: Set up custom error handling strategies.

Developer Guide
===============

This section is intended for developers who want to contribute to the OpenAPI project or create their own APIs.

1. **Fork the Repository**:
   Start by forking our GitHub repository to your own account.

2. **Set Up Your Development Environment**:
   Clone the repository and install necessary dependencies.

3. **Define Your API**:
   Use the OpenAPI Specification to define your new API endpoints, request/response models, and other components.

4. **Test Your API**:
   Ensure your API works as expected by writing and running tests.

5. **Document Your API**:
   Update the documentation to include your new API endpoints and any relevant information.

6. **Submit a Pull Request**:
   Once your changes are complete, submit a pull request for review.
