<!-- Source: https://github.com/arduino/tooling-project-assets/blob/main/other/installation-script/installation.md -->
Several options are available for installation of Arduino CLI. Instructions for each are provided below:
## Install via Homebrew (macOS/Linux)
The Arduino CLI is available as a Homebrew formula since version `0.5.0`:
```sh
brew update
brew install arduino-cli
```
### Command line completion
[Command line completion](command-line-completion.md#brew) files are already bundled in the homebrew installation.
## Use the install script
The script requires `sh`, which is always available on Linux and macOS. `sh` is not available by default on Windows,
though it is available as part of [Git for Windows](https://gitforwindows.org/) (Git Bash). If you don't have `sh`
available, use the ["Download" installation option](#download).
This script will install the latest version of Arduino CLI to `$PWD/bin`:
```
curl -fsSL https://raw.githubusercontent.com/arduino/arduino-cli/master/install.sh | sh
```
If you want to target a different directory, for example `~/local/bin`, set the `BINDIR` environment variable like this:
```
curl -fsSL https://raw.githubusercontent.com/arduino/arduino-cli/master/install.sh | BINDIR=~/local/bin sh
```
If you would like to use the `arduino-cli` command from any location, install Arduino CLI to a directory already in your
[`PATH`](https://en.wikipedia.org/wiki/PATH%5F%28variable%29) or add the Arduino CLI installation path to your `PATH`
environment variable.
If you want to download a specific Arduino CLI version, for example `0.9.0` or `nightly-latest`, pass the version number
as a parameter like this:
```
curl -fsSL https://raw.githubusercontent.com/arduino/arduino-cli/master/install.sh | sh -s 0.9.0
```
Arduino CLI checks for new releases every 24 hours. If you don't like this behaviour you can disable it by setting the
[`updater.enable_notification` config](configuration.md#configuration-keys) or the
[env var `ARDUINO_UPDATER_ENABLE_NOTIFICATION`](configuration.md#environment-variables) to `false`.
## Download
Pre-built binaries for all the supported platforms are available for download from the links below.
If you would like to use the `arduino-cli` command from any location, extract the downloaded file to a directory already
in your [`PATH`](https://en.wikipedia.org/wiki/PATH%5F%28variable%29) or add the Arduino CLI installation path to your
`PATH` environment variable.

> These links return a `302: Found` response, redirecting to latest generated builds by replacing `latest` with the
> latest available build date, using the format YYYYMMDD (i.e for 2019-08-06 `latest` is replaced with `20190806` )
Checksums for the nightly builds are available at
`https://downloads.arduino.cc/arduino-cli/nightly/nightly-<DATE>-checksums.txt`
## Build from source
If you're familiar with Golang or if you want to contribute to the project, you will probably build Arduino CLI locally
with your Go toolchain. See the ["How to contribute"](CONTRIBUTING.md#building-the-source-code) page for instructions.
