You can install the AWS Copilot CLI by using Homebrew or by manually downloading the binary with the following steps.

## Use Homebrew
<a name="copilot-install-homebrew"></a>

The following command is used to install the AWS Copilot CLI on your macOS or Linux system using Homebrew. Before installation, you should have Homebrew installed. For more information, see [Homebrew](https://brew.sh/).

```
brew install aws/tap/copilot-cli
```

## Download binary
<a name="copilot-install-manual"></a>

As an alternative to Homebrew, you can manually install the AWS Copilot CLI on your macOS, Windows, or Linux system. Use the following command for your operating system to download the binary. The macOS and Linux examples also include commands that apply execute permissions to the binary, and list the help menu to verify that the installation works.

------

```

------
#### [ Windows ]

Using Powershell, run the following command:

```
New-Item -Path 'C:\copilot' -ItemType directory; `
  Invoke-WebRequest -OutFile 'C:\copilot\copilot.exe' https://github.com/aws/copilot-cli/releases/latest/download/copilot-windows.exe
```

------

### (Optional) Verify the manually installed AWS Copilot CLI using PGP signatures
<a name="ECS_Copilot_validate"></a>

The AWS Copilot CLI executables are cryptographically signed using PGP signatures. The PGP signatures can be used to verify the validity of the AWS Copilot CLI executable. Use the following steps to verify the signatures using the GnuPG tool.

1. Download and install GnuPG. For more information, see the [GnuPG website](https://www.gnupg.org).

------
#### [ macOS ]

   We recommend using Homebrew. Install Homebrew using the instructions from their website. For more information, see [Homebrew](https://brew.sh/). After Homebrew is installed, use the following command from your macOS terminal.

   ```
   brew install gnupg
   ```

------
#### [ Linux ]

   Install `gpg` using the package manager on your flavor of Linux.

------
#### [ Windows ]

   Download the Windows simple installer from the GnuPG website and install as an Administrator. After you install GnuPG, close and reopen the Administrator PowerShell.

    For more information, see [GnuPG Download](https://www.gnupg.org/download/index.html).

------

1. Verify the GnuPG path is added to your environment path.

------
#### [ macOS ]

   ```
   echo $PATH
   ```

   If you do not see the GnuPG path in the output, run the following command to add it to the path.

   ```
   PATH=$PATH:<path to GnuPG executable files>
   ```

------
#### [ Linux ]

   ```
   echo $PATH
   ```

   If you do not see the GnuPG path in the output, run the following command to add it to the path.

   ```
   export PATH=$PATH:<path to GnuPG executable files>
   ```

------
#### [ Windows ]

   ```
   Write-Output $Env:PATH
   ```

   If you do not see the GnuPG path in the output, run the following command to add it to the path.

   ```
   $Env:PATH += ";<path to GnuPG executable files>"
   ```

------

1. Create a local plain text file.

------
#### [ macOS ]

   On the terminal, enter:

   ```
   touch <public_key_filename.txt>
   ```

   Open the file with TextEdit.

------
#### [ Linux ]

   Create a text file in a text editor such as gedit. Save as `public_key_filename.txt`

------
#### [ Windows ]

   Create a text file in a text editor such as Notepad. Save as `public_key_filename.txt`

------

1. Add the following contents of the Amazon ECS PGP public key and save the file. 

   ```

   + For Windows systems:

     ```
     gpg --verify 'C:\copilot\copilot.asc' 'C:\copilot\copilot.exe'
     ```

   Expected output:

   ```
   gpg: Signature made Tue Apr  3 13:29:30 2018 PDT
   gpg:                using RSA key DE3CBD61ADAF8B8E
   gpg: Good signature from "Amazon ECS <ecs-security@amazon.com>" [unknown]
   gpg: WARNING: This key is not certified with a trusted signature!
   gpg:          There is no indication that the signature belongs to the owner.
   Primary key fingerprint: F34C 3DDA E729 26B0 79BE  AEC6 BCE9 D9A4 2D51 784F
        Subkey fingerprint: EB3D F841 E2C9 212A 2BD4  2232 DE3C BD61 ADAF 8B8E
   ```
**Important**  
The warning in the output is expected and is not problematic. It occurs because there is not a chain of trust between your personal PGP key (if you have one) and the Amazon ECS PGP key. For more information, see [Web of trust](https://en.wikipedia.org/wiki/Web_of_trust).

1. For Windows installations, run the following command on Powershell to add AWS Copilot directory to the path.

   ```
    $Env:PATH += ";<path to Copilot executable files>"
   ```
