Hi. I have started using trello as the source for my documentation. The nice thing is that I can really structure the content well in a way that makes sense to describe partially complex scenarios. It also forces you to make real good headings, which can help you in longtail SEO. When the trello doc is pretty much clean I get the JSON of the trello board and convert it to markdown.
I love markdown. Markdown keeps your content very clean. So a trello board represents an article in the igumbi documentation. To do the markdown conversion I have this small `ruby script (GIST).
I have just recently started with this process, but I am really liking it. Especially as you can invite others to contribute to your trello board, so the documentation will evolve without too much pain (I hope)
See some examples of the support articles (in German): “Anzahlung Verwalten” or a lengthy one without screenshots, still prepping them ): “Channel Manager mit igumbi Hotelsoftware verbinden”
For screenshots/images my CMS has a tag, so I can reference them in the Markdown Texts I enter in trello.
The nice thing is that I can later repurpose the Markdown Files to compile a PDF Version using Marked (A Mac Markdown tool.
