[Article] Gelato functions on Mode

[joshuanwankwo]

Task Description:

We need to create a technical written piece that could be added to the documentation but also post as an article on mirror.

The focus is to showcase a simple use case for the functions that Gelato provides and how to do it as a step-by-step guide.

Also, while doing the article the Gelato functions should be tested and report back any problems found along the way.

Acceptance Criteria:

• Length and Depth: Minimum of 800 words, ensuring in-depth coverage of the topic.
• Formatting: Clear structure with headings, subheadings, and bullet points for easy reading.
• Visuals: This is not a must, but it's a plus if it includes relevant images, diagrams, or code snippets where applicable.
• Language and Style: Professional, engaging, and free of grammatical errors.
