Create sidebar contents based off of contents within subfolder

[delize]

I am trying to create a documentation page using minimal mistakes, and utilizing the sidebar to do so. The one thing that I am trying to avoid however, is creating manual sidebar entries, and would prefer to have everything statically created based off the pages/posts within the a folder.

Index
|
|
- Docs
   |   - "Geting Started"
          |   - Getting Started Page 1.md
          |   - Getting Started Page 2.md
   |   - "Product Feature 1"
          |   - How to do XYZ.md
          |   - What if ABC happens.md
   |   - "Product Feature 2" 
          |   - Example page 3.md
   |   - etc
- Some other subfolder

Something to the extent like above. Rather than having to type in each folder, as far as I can tell, there should be a way to do this with Jekyll reading each.

Collections doesn't really apply or assist with this, as each .md file is it's own piece, of documentation and not a lot of it will need to be re-purposed or reused.

Is there a better solution to this method of creating a statically generated sidebar then typing each title/sub-item by hand?
