 It unifies Electron's build tooling ecosystem into
 a single extensible interface so that anyone can jump right into making Electron apps.

+<summary>Alternative tooling</summary>
+
+If you do not want to use Electron Forge for your project, there are other
+third-party tools you can use to distribute your app.
+
+These tools are maintained by members of the Electron community,
+and do not come with official support from the Electron project.
+
+**Electron Builder**
+
+A "complete solution to package and build a ready-for-distribution Electron app"
+that focuses on an integrated experience. [`electron-builder`](https://github.com/electron-userland/electron-builder) adds a single dependency and manages all further requirements internally.
+
+`electron-builder` replaces features and modules used by the Electron
+maintainers (such as the auto-updater) with custom ones.
+
+**Hydraulic Conveyor**
+
+A [desktop app deployment tool](https://hydraulic.dev) that supports
+cross-building/signing of all packages from any OS without the need for
+multi-platform CI, can do synchronous web-style updates on each start
+of the app, requires no code changes, can use plain HTTP servers for updates and
+which focuses on ease of use. Conveyor replaces the Electron auto-updaters
+with Sparkle on macOS, MSIX on Windows, and Linux package repositories.
+
+Conveyor is a commercial tool that is free for open source projects. There's
+an example of [how to package GitHub Desktop](https://hydraulic.dev/blog/8-packaging-electron-apps.html)
+which can be used for learning.

 ## Getting started
 
 The [Electron Forge docs][] contain detailed information on taking your application
 from source code to your end users' machines.
 This includes:
 
-* Packaging your application [(package)][]
-* Generating executables and installers for each OS [(make)][], and,
-* Publishing these files to online platforms to download [(publish)][].

 For beginners, we recommend following through Electron's [tutorial][] to develop, build,
 package and publish your first Electron app. If you have already developed an app on your machine
 and want to start on packaging and distribution, start from [step 5][] of the tutorial.
