The Open Source Overlay Networking Tool

Interested in creating an overlay network of your own? You’re in the right place. Welcome!

When Nebula was open sourced, we did our best to include clear and concise documentation within the README and configuration files published along with the source code.

GitHub Project (slackhq/nebula) 

After a few months of fielding questions about how to get Nebula working it became clear that we needed to expand the official documentation for the project.

Here is where you’ll find detail about each of the major components in Nebula’s architecture, how they fit together, and how to make them work best in a variety of environments and use cases.
