<PropertyGroup>
<TargetFramework>net6.0</TargetFramework>
</PropertyGroup>
<Import Project="addons\Nebula\Nebula.props" />

Nebula is a library for developing online multiplayer games with Godot. It is a tick-aligned system, respects input authority, and all state is managed by the server.
This library is still in BETA, therefore it is not quite production-ready and is subject to changes as we approach stability.
