# Built-in Libraries

Lune contains a large set of built-in libraries, much like Luau itself. These libraries include, but
are not limited to, these libraries and their common use cases:

-   The [`fs`](../../api-reference/fs.md) library for manipulating files
-   The [`net`](../../api-reference/net.md) library for making HTTP requests
-   The [`process`](../../api-reference/process.md) library for executing external programs and
    processes

This is just a small subset of what is available in Lune, but for now, what is important is that
these libraries must be imported using a special kind of `require` statement:

```lua copy
local fs = require("@lune/fs")
local net = require("@lune/net")
local process = require("@lune/process")
```

As you can see above, unlike Luau's standard libraries such as
[`math`](https://luau-lang.org/library#math-library),
[`table`](https://luau-lang.org/library#table-library),
[`string`](https://luau-lang.org/library#string-library), and others, Lune's built-in libraries are
not available as global variables and importing them before using them is required (pun intended).

The next few sections will contain examples of how to run scripts, more specific usage of Lune's
built-in libraries, and what they are most commonly used for.
