I also have a side project called Docs Like Code. The site is specifically focused on best practices and lessons learned about applying software dev techniques and tools to software documentation. I want to learn and teach at the same time as I keep exploring this space.
If you want to see a bit of how the site is put together, and how you can use GitHub to make web sites, join in. There’s an email list with some lessons and a free PDF checklist offer just for signing up.
In the meantime, take a look at this quick less-than-five-minute look at how you can build Jekyll sites locally.
