+## Introduction
+
+The hilbish.module interface provides a function to load
+Hilbish plugins/modules. Hilbish modules are Go-written
+plugins (see https://pkg.go.dev/plugin) that are used to add functionality
+to Hilbish that cannot be written in Lua for any reason.
+
+Note that you don't ever need to use the load function that is here as
+modules can be loaded with a `require` call like Lua C modules, and the
+search paths can be changed with the `paths` property here.
+
+To make a valid native module, the Go plugin has to export a Loader function
+with a signature like so: `func(*rt.Runtime) rt.Value`.
+
+`rt` in this case refers to the Runtime type at
+https://pkg.go.dev/github.com/arnodel/golua@master/runtime#Runtime
+
+Hilbish uses this package as its Lua runtime. You will need to read
+it to use it for a native plugin.
+
+Here is some code for an example plugin:
+```go
+package main
+
+import (
+	rt "github.com/arnodel/golua/runtime"
+)
+
+func Loader(rtm *rt.Runtime) rt.Value {
+	return rt.StringValue("hello world!")
+}
+```
+
+This can be compiled with `go build -buildmode=plugin plugin.go`.
+If you attempt to require and print the result (`print(require 'plugin')`), it will show "hello world!"

 # Why?
 Hilbish emerged from the desire of a Lua configured shell.
 It was the initial reason that it was created, but now it's more:
 to be hyper extensible, simpler and more user friendly.
+
+# Does it have "autocompletion" or "tab completion"
+Of course! This is a modern shell. Hilbish provides a way for users
+to write tab completion for any command and/or the whole shell.
+Inline hinting and syntax highlighting are also available.

+// #field paths A list of paths to search when loading native modules. This is in the style of Lua search paths and will be used when requiring native modules. Example: `?.so;?/?.so`
+/*
+The hilbish.module interface provides a function to load
+Hilbish plugins/modules. Hilbish modules are Go-written
+plugins (see https://pkg.go.dev/plugin) that are used to add functionality
+to Hilbish that cannot be written in Lua for any reason.
+
+Note that you don't ever need to use the load function that is here as
+modules can be loaded with a `require` call like Lua C modules, and the
+search paths can be changed with the `paths` property here.
+
+To make a valid native module, the Go plugin has to export a Loader function
+with a signature like so: `func(*rt.Runtime) rt.Value`.
+
+`rt` in this case refers to the Runtime type at
+https://pkg.go.dev/github.com/arnodel/golua@master/runtime#Runtime
+
+Hilbish uses this package as its Lua runtime. You will need to read
+it to use it for a native plugin.
+
+Here is some code for an example plugin:
+```go
+package main
+
+import (
+	rt "github.com/arnodel/golua/runtime"
+)
+
+func Loader(rtm *rt.Runtime) rt.Value {
+	return rt.StringValue("hello world!")
+}
+```
+
+This can be compiled with `go build -buildmode=plugin plugin.go`.
+If you attempt to require and print the result (`print(require 'plugin')`), it will show "hello world!"
