I've been developing educational materials for a long time now, but I don't know where to share them.

I have a selection of textbooks (PDFs) that can assist in various contexts.

• Some US army textbooks
• Some field medical books
• Books on theory

I also have materials I've made myself (i.e. Operational Security, FOSS alternatives, etc).

But where I'm at, I don't think I have the community that would appreciate anything I have to give.

Where should I put my stuff? Ideally someplace where I can continuously contribute to it.

I've even come across good stuff on learning to drone, learning to quadcopter. But there should be some place to develop the materials. Especially someplace others can help contribute to that.
