Hi, I'm an experienced technical writer looking to expand my portfolio of writing samples. I can help you with this if you can provide me with a summary of the problems and solutions you want documented. I've taken a look at your current documentation, and I'm comfortable with Markdown, so I'm sure I can help out.
