# Install Avalanche-CLI

## Build Your First Subnet

The first step of learning Subnet development is learning to use [Avalanche-CLI](https://github.com/ava-labs/avalanche-cli).

The best way to get started is by jumping in and deploying your first Subnet.

This tutorial walks you through the process of using Avalanche-CLI for the first time by creating a Subnet, deploying it to the local network, and connecting to it with MetaMask.

### Installation

The fastest way to install the latest Avalanche-CLI binary is by running the install script:

```shell
curl -sSfL https://raw.githubusercontent.com/ava-labs/avalanche-cli/main/scripts/install.sh | sh -s
```

The binary installs inside the `~/bin` directory. If the directory doesn't exist, it will be created.

You can run all of the commands in this tutorial by calling `~/bin/avalanche`.

You can also add the command to your system path by running

```shell
export PATH=~/bin:$PATH
```

If you add it to your path, you should be able to call the program anywhere with just `avalanche`. To add it to your path permanently, add an export command to your shell initialization script (ex: .bashrc or .zshrc).

For more detailed installation instructions, see Avalanche-CLI Installation

To add it to your path permanently, add an export command to your shell initialization script. If you run `bash`, use `.bashrc`. If you run `zsh`, use `.zshrc`.

For example:

```
export PATH=~/bin:$PATH >> .bashrc
```

### Checking Your Installation[​](https://docs.avax.network/subnets/install-avalanche-cli#checking-your-installation) <a href="#checking-your-installation" id="checking-your-installation"></a>

You can test your installation by running `avalanche --version`. The tool should print the running version.

### Updating[​](https://docs.avax.network/subnets/install-avalanche-cli#updating) <a href="#updating" id="updating"></a>

To update your installation, you need to delete your current binary and download the latest version using the preceding steps.

### Building from Source[​](https://docs.avax.network/subnets/install-avalanche-cli#building-from-source) <a href="#building-from-source" id="building-from-source"></a>

The source code is available in this [GitHub repository](https://github.com/ava-labs/avalanche-cli).

After you've cloned the repository, checkout the tag you'd like to run. You can compile the code by running `./scripts/build.sh` from the top level directory.

The build script names the binary `./bin/avalanche`.
