Title
Description
Everyone says that a picture is worth a thousand words... The issue in the past is that those pictures have been hard to create let alone maintain. Welcome Mermaid (https://mermaid-js.github.io/mermaid/#/)! Mermaid is a mark down compatible graphing tool that allows you to add diagrams directly to your markdown in github. I have been using it for a a year and just love it. I believe that you will love it too once you join my session.

Summary
Markdown supported
In this engaging session from RubyConf 2022, Carolyn Cole from Princeton University Library presents her enthusiasm for Mermaid JS, a diagramming tool designed for creating visual representations directly within Markdown files, particularly in GitHub. The presentation explores the key features and benefits of Mermaid JS, demonstrating its application through diagrams that enhance documentation and system clarity. Key Points Discussed: - **Overview of Mermaid JS:** Carolyn introduces Mermaid JS as a tool for creating code-based diagrams, which are easier to maintain and integrate within documentation. - **Accessibility and Documentation:** She emphasizes the importance of titles for diagrams to enhance accessibility and how they help in documenting systems effectively for current and future developers. - **Example Diagrams:** Carolyn shares various diagrams, including state and sequence diagrams, detailing how they clarify complex interactions within systems. For instance, she shows a state diagram that visually represents the flow of different states, making it clearer than text alone. - **Creating Diagrams with Mermaid:** The presentation transitions into a live demo where Carolyn builds a sequence diagram, showcasing how user interactions lead to object creation and metadata updates in a system, all while emphasizing the simplicity of using Mermaid for code-based diagrams. - **Expanded Functionality:** Carolyn highlights Mermaid’s features, including alternate logic for branching scenarios and the ability to incorporate roles like curators in documentation workflows, enhancing the complexity of diagrams to suit varying requirements. - **Visual Presentation and Themes:** She explains how Mermaid allows for customization in diagrams through theming and color-coding, helping to visually differentiate sections and improve clarity. - **Community Contributions and Resources:** Throughout the session, Carolyn references resources, including a cheat sheet she developed for easier navigation of Mermaid’s extensive documentation. Conclusion and Takeaways: - Carolyn concludes by reiterating the immense value of Mermaid JS in fostering clearer communication and documentation practices within coding environments. - She encourages the audience to explore Mermaid for themselves, sharing a QR code link to access her presentation slides and resources for further learning. - The Q&A session addresses questions about integrating icons and functionalities related to GitHub, reinforcing Mermaid JS's versatility in technical documentation. Overall, this session effectively showcases how Mermaid JS can enhance the clarity and maintainability of project documentation through visual diagrams, while also promoting collaboration and understanding amongst developers.
