Ask HN: What are you using for public documentation these days?
We are using Docusaurus (https://docusaurus.io/ ).   - it is easy to configure/customise 
   - looks really great out of the box
   - solid documentation
   - fast

In our case, we just had to change the colors and font.   Here is our Docusaurus code if that's helpful: https://github.com/ToolJet/ToolJet/tree/develop/docs and here is the   live documentation: https://docs.tooljet.com/
