How to publish Extension to the Web Store
When your first Chrome extension looks beautiful and works as it should (how to install extension locally?), it’s time to publish extension in the Chrome Store. Just follow this link to go to the Chrome Web Store Dashboard (you’ll be prompted to log in to your Google account if it’s not). Then click on the “Add new item” button, accept the terms and you will be taken to a page where you can upload the extension. Now compress the folder containing your project and upload ZIP file.
After successfully uploading the file, you will see a form in which you should add some information about your extension. You can add an icon, a detailed description, upload some screenshots and so on.
Make sure you provide some good images to show off your project. The store can use these images to promote your innovative project. The more images you provide, the more noticeable your extension will be. You can see how your extension is shown in the Web Store by clicking the “Preview” button. When you are happy with the result, click Publish Extension. Done!
It remains only to get users!
