# Introduction
[Wasmtime][github] is a standalone optimizing runtime for [WebAssembly],
[the Component Model], and [WASI] by the [Bytecode Alliance][BA]. It runs
WebAssembly code [outside of the Web], and can be used both as a command-line
utility or as a library embedded in a larger application. Wasmtime strives to be
a highly configurable and embeddable runtime to run on any scale of application.
This documentation is intended to serve a number of purposes and within you'll
find:
* [How to use Wasmtime from a number of languages](lang.md)
* [How to install and use the `wasmtime` CLI](cli.md)
* Information about [stability](stability.md) and [security](security.md) in
Wasmtime.
* Documentation about [contributing](contributing.md) to Wasmtime.
