+## Unreleased
+
+### Added
+
+- Added a new `luau` built-in library for manually compiling and loading Luau source code. ([#82])
+
+  Example usage:
+
+  ```lua
+  local luau = require("@lune/luau")
+
+  local bytecode = luau.compile("print('Hello, World!')")
+  local callableFn = luau.load(bytecode)
+
+  callableFn()
+
+  -- Additionally, we can skip the bytecode generation and
+  -- load a callable function directly from the code itself.
+  local callableFn2 = luau.load("print('Hello, World!')")
+
+  callableFn2()
+  ```
