The "Publish" button is located in the top right corner of the v0 interface, specifically:

1. In the Code Project view - When you're looking at your code, look for the publish/deploy button in the top right toolbar
2. Next to other action buttons - It should be near the GitHub logo button and the three dots menu

If you don't see a "Publish" button, it might be labeled as:

• "Deploy"
• "Deploy to Vercel"
• Or represented by a rocket icon 🚀

Alternative ways to deploy:

• Click the three dots (⋯) in the top right → Look for deployment options
• Download ZIP option (also in the three dots menu) → Then upload to your own hosting

If you're still having trouble finding it, you can also:

1. Download your project as a ZIP file
2. Push to GitHub (using the GitHub button)
3. Then deploy from there to Vercel, Netlify, or other platforms

Are you able to see the publish/deploy button in your interface, or would you like me to help you with an alternative deployment method?

On mobile, the v0 interface is more compact, so the publish button might be in a different location:

On Mobile v0:

• Tap the menu icon (☰ or three lines) in the top right
• Look for "Deploy" or "Publish" in the dropdown menu
• Check for a rocket icon 🚀 in the top toolbar

If mobile interface is limited:

• Switch to desktop view - Most mobile browsers have a "Request Desktop Site" option
• Use a computer/laptop - Full v0 interface has all deployment options
• Download the project - Get the ZIP file and deploy later from desktop

Alternative mobile-friendly deployment:

1. Push to GitHub (if available on mobile)
2. Connect GitHub to Vercel - Deploy automatically from your phone's browser
3. Use Vercel mobile app - If they have one for managing deployments

Quick mobile workaround:

• Share your v0 project link with yourself
• Open on desktop later to deploy
• Or ask someone with desktop access to help deploy it

The mobile web interface for development tools is often limited, so using a desktop or laptop is usually the easiest way to deploy your app.

Would you like me to help you with any of these options, or do you have access to a desktop to deploy your e-commerce app?
