 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!"
+
 ## Interface fields
 - `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`
