# Pre-requisites

### **Pre-requisites**

Berry is based on `nodejs.` Please check the following **prerequisites** before jumping on it.

In your command terminal and check using the **`node -v`** command

```bash
node -v
v24.13.0
```

**Package Manager** - npm or yarn

```bash
yarn -v
1.22.22
```

### **Troubleshooting**

If you face the following error in your terminal, it means **Yarn** is not installed in your system.

<pre class="language-bash"><code class="lang-bash">yarn -v
<strong>'yarn' is not recognized as an internal or external command,
</strong>operable program or batch file.
</code></pre>

Please install it using this [link](https://yarnpkg.com/getting-started/install) as it does not come with **Node** automatically.
