**Nylas Mail is an open-source mail client built on the modern web with [Electron](https://github.com/atom/electron), [React](https://facebook.github.io/react/), and [Flux](https://facebook.github.io/flux/).** It is designed to be extensible, so it's easy to create new experiences and workflows around email.

You can download compiled versions of Nylas Mail for Windows, Mac OS X, and Linux (.deb) from [https://nylas.com/download](https://nylas.com/download). You can also build and run Nylas Mail (Previously N1) on Fedora. On Arch Linux, you can install **[n1](https://aur.archlinux.org/packages/n1/)** or **[n1-git](https://aur.archlinux.org/packages/n1-git/)** from the aur.
Plugins lie at the heart of Nylas Mail and give it its powerful features. Building your own plugins allows you to integrate the app with other tools, experiment with new workflows, and more. Follow the [Getting Started guide](https://nylas.github.io/nylas-mail/) to write your first plugin in five minutes. To create your own theme, go to our [Theme Starter guide](https://github.com/nylas/N1-theme-starter).
The Nylas Mail user interface is styled using CSS, which means it's easy to modify and extend. Nylas Mail comes stock with a few beautiful themes, and there are many more which have been built by community developers

Note these are not tested or officially supported by Nylas, but we still think they are really cool! If you find bugs with them, please open GitHub issues on their individual project pages, not the Nylas Mail (N1) repo page. Thanks!
When you install packages, they're moved to ~/.nylas-mail/packages, and Nylas Mail runs apm install on the command line to fetch dependencies listed in the package's package.json
You can configure Nylas Mail in a few ways—for instance, pointing it to your self-hosted instance of the sync engine or changing the interface zoom level. [Learn more about how.](https://github.com/nylas/nylas-mail/blob/master/CONFIGURATION.md)
