# Installing `wasmtime`

Here we'll show you how to install the `wasmtime` command line tool. Note that
this is distinct from embedding the Wasmtime project into another, for that
you'll want to consult the [embedding documentation](embed.md).

The easiest way to install the `wasmtime` CLI tool is through our installation
script. Linux and macOS users can execute the following:

```sh
$ curl https://wasmtime.dev/install.sh -sSf | bash
```

This will download a precompiled version of `wasmtime` and place it in
`$HOME/.wasmtime`, and update your shell configuration to place the right
directory in `PATH`.

Windows users will want to visit our [releases page][releases] and can download
the MSI installer (`wasmtime-dev-x86_64-windows.msi` for example) and use that
to install.

[releases]: https://github.com/bytecodealliance/wasmtime/releases

You can confirm your installation works by executing:

```sh
$ wasmtime -V
wasmtime 0.12.0
```

And now you're off to the races! Be sure to check out the [various CLI
options](cli-options.md) as well.

## Download Precompiled Binaries

If you'd prefer to not use an installation script, or you're perhaps
orchestrating something in CI, you can also download one of our precompiled
binaries of `wasmtime`. We have two channels of releases right now for
precompiled binaries:

1. Each tagged release will have a full set of release artifacts on the [GitHub
   releases page][releases].
2. The [`dev` release] is also continuously updated with the latest build of the
   `master` branch. If you want the latest-and-greatest and don't mind a bit of
   instability, this is the release for you.

[`dev` release]: https://github.com/bytecodealliance/wasmtime/releases/tag/dev

When downloading binaries you'll likely want one of the following archives (for
the `dev` release)

* Linux users - [`wasmtime-dev-x86_64-linux.tar.xz`]
* macOS users - [`wasmtime-dev-x86_64-macos.tar.xz`]
* Windows users - [`wasmtime-dev-x86_64-windows.zip`]

Each of these archives has a `wasmtime` binary placed inside which can be
executed normally as the CLI would.

[wasmtime-dev-x86_64-macos.tar.xz`]: https://github.com/bytecodealliance/wasmtime/releases/download/dev/wasmtime-dev-x86_64-macos.tar.xz
[wasmtime-dev-x86_64-windows.zip`]: https://github.com/bytecodealliance/wasmtime/releases/download/dev/wasmtime-dev-x86_64-windows.zip

## Compiling from Source

If you'd prefer to compile the `wasmtime` CLI from source, you'll want to
consult the [contributing documentation for building](contributing-building.md).
Be sure to use a `--release` build if you're curious to do benchmarking!
