„Any fool can know. The point is to understand.“— Albert Einstein
BookStack is a simple and easy to use Wiki database platform. I use it to document and share lots of IT knowledge.
This is the place where you can find my documentation to see how I set up my network and server to host all of this. I stick to local, self-hosted models whenever possible and always verify every single word before publishing.
For your own homelab, you are welcome to just steal what works for you.
People with a BookStack account and the right permissions do have access to more than just this documentation.
