# Lua SDK

The [Lua](https://en.wikipedia.org/wiki/Lua) SDK is available in [all editions](https://tacview.net/features/comparison/) of Tacview. That means that anyone can write and/or run add-ons written by themselves and others in Lua.

Find the Lua SDK at `C:\Program Files (x86)\Tacview\AddOns\` .

Here you will find the files `Tacview Core Interface.txt` and `Tacview Main Interface.txt` containing the reference documentation for the API, as well as about a dozen tutorials and the source code of several add-ons included with Tacview.

Find the source code of additional add-ons on our [GitHub](https://github.com/RaiaSoftwareInc/tacview.add-ons.lua).

Even if you are programmimg in [C++/C#](/tacview/sdk/cpp-cs.md), this documentation will be helpful to you, because the APIs are basically identical.
