+## Welcome to Mintlify
+
+Get your documentation site up and running in just a few minutes with this quickstart guide.
+
+## Prerequisites
+
+Before you begin, make sure you have:
+- A GitHub account
+- Basic familiarity with Markdown
+- Your documentation content ready
+
+## Step 1: Create your documentation
+
+<Steps>
+  <Step title="Initialize your project">
+    Start by creating a new repository or using an existing one for your documentation.
+    
+    ```bash
+    mkdir my-docs
+    cd my-docs
+    ```
+  </Step>
+
+  <Step title="Add your first page">
+    Create an `index.mdx` file in your project root:
+    
+    ```mdx index.mdx
+    ---
+    title: Welcome
+    description: Welcome to my documentation
+    ---
+    
+    # Welcome to my docs
+    
+    This is your first documentation page.
+    ```
+  </Step>
+
+  <Step title="Configure navigation">
+    Create a `docs.json` file to configure your site:
+    
+    ```json docs.json
+    {
+      "name": "My Documentation",
+      "navigation": {
+        "pages": ["index"]
+      }
+    }
