Documentation Skills​

  • Clear and concise documentation is crucial in software development. This includes not only code comments and README files, but also blog posts and articles that share your knowledge with others.

Here are some key skills and tools to master:

  • Markdown - A lightweight markup language that you can use to write easy-to-read and easy-to-write plain text format, which then converts to structurally valid HTML. It's widely used for README files, documentation, and writing articles on platforms like GitHub and Jekyll blogs.

  • Mermaid.js - A JavaScript library that allows you to create diagrams and flowcharts using text. It integrates well with Markdown, making it great for blog posts that need to explain complex ideas visually.

  • Language Server Protocol - A protocol developed by Microsoft that allows code editing tools to provide features like auto-complete, go to definition, find all references and alike without each tool needing to understand each programming language.

  • Diagram as a Code - A Python library that allows you to create diagrams using code, which is great for prototyping a new system architecture design or explaining system design in your blog posts.

Remember, good documentation skills involve clear communication, good organization, and the ability to explain complex ideas in a simple, understandable way. Practice writing blog posts and articles to improve these skills. You can also contribute to open-source projects by writing documentation for them. Maintain documentation in tools like Dendron, Logseq which is a powerful note-taking system that allows you to organize and navigate your knowledge effectively.

Once a big knowledge base is built, you can use it to capture coding patterns, solutions to common problems, and snippets of code. Combine it with Markdown files and notebook tools like Jupyter Notebook (NB) to create well-structured and executable documentation. This approach will streamline your workflow and serve as a valuable resource for future reference which can be used with Large Language Models to gain insights.

Consider all documentation as a code. Refer to my blog post Documentation as Code for more information.
