+# lu9 -- Lua for Plan 9 space
+
+lu9 is an umbrella project providing a native Plan 9 port of the Lua
+library and several other libraries and programs built on top of it.
+
+The project is currently comprised of the following:
+
+* [lu9](https://git.sr.ht/~kvik/lu9) is a simple Lua interpreter
+ host intended for running standalone Lua programs and interactive
+ usage. It also serves as an example on how to use the Lua library
+ in your own programs.
+* [lu9-lua](https://git.sr.ht/~kvik/lu9-lua) is a Lua 5.4 library
+ patched to work well within the Plan 9 environment. It does not
+ depend on any other code in this project.
+ Unlike many previous ports it does *NOT* use APE, the POSIX
+ emulation layer, which means that you can use it alongside regular
+ Plan 9 libraries.
+* [lu9-p9](https://git.sr.ht/~kvik/lu9-p9) is a system interface
+ module providing access to system calls and other useful libc
+ interfaces. It also provides some higher-level interfaces for
+ the most common tasks.
+* [lu9-lpeg](https://git.sr.ht/~kvik/lu9-lpeg) is a simple port
+ of the LPeg pattern matching module.
+
+Check the respective repositories for more information.

+
+### Building and installing
+
+Building and installing lu9 is simple: clone this repository and run
+`mk install`. The build will automatically clone and build all the
+dependencies.
+
+ ; git/clone https://git.sr.ht/~kvik/lu9
+ ; mk install
+
+Only lu9 binary and Lua modules get installed into the system.
+The binary is statically linked so no C libraries have to be installed.
+
+The provided `mkfile` can pull any updates to lu9 and its dependencies.
+
+ ; mk pull
+ ; mk install
+
+### Usage
+
+Check the [lu9(1) manual page](http://a-b.xyz/man/1/lu9) for more
+information.
