# Lua # Lush
This is the repository of Lua development code, as seen by the Lua team. It contains the full history of all commits but is mirrored irregularly. For complete information about Lua, visit [Lua.org](https://www.lua.org/). Lush is a shell built on [Lua 5.5.0](https://www.lua.org/). It extends Lua with shell-oriented features like command execution, pipelines, and built-in shell commands while maintaining full compatibility with the Lua 5.5 ecosystem.
Please **do not** send pull requests. To report issues, post a message to the [Lua mailing list](https://www.lua.org/lua-l.html). Based on [Lua](https://www.lua.org/) by R. Ierusalimschy, L. H. de Figueiredo, W. Celes (PUC-Rio).
Download official Lua releases from [Lua.org](https://www.lua.org/download.html).
