Create an "Online Usage Guide" section in the documentation

[lkhamvongsa]

Current state

The current Wasm4learn documentation lacks a dedicated section that focuses on online usage. I propose adding an "Online Usage Guide" to provide users with clear instructions on how to access and use Wasm4learn directly in a browser.

Goals

• Offer a step-by-step guide for using Wasm4learn in an online environment.
• Include practical examples of how to run and interact with Wasm4learn online.
• Provide troubleshooting steps or a FAQ for common online usage issues.

Tasks

• Organize the section with clear subsections for accessing and navigating the online platform.
• Write detailed instructions specific to web-based usage.
• Add practical examples demonstrating the online functionalities.
• Create a "FAQ" or "Common Issues" section focused on online usage.
• Benefits: This section will help users quickly understand how to use Wasm4learn directly in their browser, making it easier for them to get started and reducing the need for support related to online access.
