## What this means
You can:
- use VNOX for any purpose
- study and modify the source code
- distribute copies of VNOX

You cannot:
- distribute VNOX or derivatives under a proprietary license
- remove copyright notices
## Protocol specification
The LNEx protocol specification (`docs/02-protocol/`) is additionally
licensed under **CC0 1.0 Universal (Public Domain)**.
This means anyone can implement the LNEx protocol in any language,
under any license, without restriction. Third-party clients and servers
are explicitly encouraged.
## Plugins
Plugins you write for VNOX are your own code. The GPL does not automatically
apply to plugin code — plugins communicate with VNOX via WebSocket RPC,
which is considered a separate program. You may license your plugins however
you choose.
