Napa is a great way to get started building Office Add-ins right in a browser window. You don't need to install any tools such as Visual Studio. All you need is an Office 365 account and a supported browser. To get started, sign up for an Office 365 Developer Site. Then, install Napa on your Developer site and you are ready to create Office Add-ins. See Set up a development environment for SharePoint Add-ins on Office 365. When you're ready to use the powerful capabilities in Visual Studio, Napa makes it easy to download your project and continue developing your Office Add-in.
There's an alternate version of Napa that doesn't use or require an Office 365 Developer Site. That version supports creating only Office Add-ins using your personal Microsoft account.
Napa gives you a page to manage your projects. You can use this page to create a mail add-in, content add-in, or task pane add-in project, rename, and delete projects. You can also open any project in Visual Studio if you decide that you want to use features such as advanced debugging or use a web project as part of your Office Add-in. Choose a filter to view recently modified projects or projects of a specific type. Choose a project tile if you want to open an existing project.
While you’re developing your add-in, if you want to share it with someone else, such as to show them code or pages you're developing, you can use the Share Project feature. To share an add-in project, load the project in Napa and then choose the Share Project button on the side of the page. The Share Project feature creates a copy of the add-in project and provides you with a public link that you can give to anyone to enable them to view the copy of the add-in project. After you’ve completed your add-in project and want to distribute it, you can publish your add-in. See Publish SharePoint Add-ins or Package your add-in using Napa or Visual Studio to prepare for publishing.
