## What it is
NLua is a .NET library that bridges the Lua scripting language with C#/.NET, allowing Lua code to be executed from .NET applications and .NET objects to be used from Lua. It is a fork of LuaInterface and runs on Windows, Linux, macOS, iOS, Android, and UWP via .NET, .NET Core, and .NET Standard.

## Use cases
- embed a Lua scripting engine in a C# application
- let users extend a .NET app with Lua scripts
- evaluate Lua expressions from C# code
- call .NET classes and methods from Lua scripts
- run game or app configuration logic written in Lua
- bind Lua functions to C# callbacks

## When to choose
- you need Lua scripting inside a .NET, Xamarin, or Unity-adjacent C# project
- you want .NET objects accessible from Lua without registration or annotations
- you need cross-platform Lua support including mobile (iOS/Android) and UWP

## When to avoid
- your project is not on the .NET platform
- you need a pure Lua runtime without .NET interop
- you need bindings for a different scripting language like Python or JavaScript
