# Application Distribution
To distribute your app with Electron, you need to package and rebrand it. The easiest way to do this is to use one of the following third party packaging tools:
## Overview
To distribute your app with Electron, you need to package and rebrand it.
To do this, you can either use specialized tooling or manual approaches.
## With tooling
You can use the following tools to distribute your application:
* [electron-forge](https://github.com/electron-userland/electron-forge)
* [electron-builder](https://github.com/electron-userland/electron-builder)
* [electron-packager](https://github.com/electron/electron-packager)
These tools will take care of all the steps you need to take to end up with a distributable Electron applications, such as packaging your application, rebranding the executable, setting the right icons and optionally creating installers.
These tools will take care of all the steps you need to take to end up with a

You can check the example of how to package your app with `electron-forge` in
our [Quick Start Guide](quick-start.md#package-and-distribute-the-application).
## Manual distribution
You can also choose to manually get your app ready for distribution. The steps needed to do this are outlined below.
### With prebuilt binaries
To distribute your app with Electron, you need to download Electron's [prebuilt
To distribute your app manually, you need to download Electron's [prebuilt
binaries](https://github.com/electron/electron/releases). Next, the folder
containing your app should be named `app` and placed in Electron's resources
directory as shown in the following examples. Note that the location of
Electron's prebuilt binaries is indicated with `electron/` in the examples
below.

Then execute `Electron.app` (or `electron` on Linux, `electron.exe` on Windows),
and Electron will start as your app. The `electron` directory will then be

## Packaging Your App into a File
### With an app source code archive
Apart from shipping your app by copying all of its source files, you can also
package your app into an [asar](https://github.com/electron/asar) archive to avoid
exposing your app's source code to users.
Instead of from shipping your app by copying all of its source files, you can
package your app into an [asar] archive to improve the performance of reading
files on platforms like Windows, if you are not already using a bundler such
as Parcel or Webpack.
To use an `asar` archive to replace the `app` folder, you need to rename the
archive to `app.asar`, and put it under Electron's resources directory like
below, and Electron will then try to read the archive and start from it.
On macOS:
*On macOS:*
```plaintext
electron/Electron.app/Contents/Resources/
└── app.asar
```
On Windows and Linux:
*On Windows and Linux:*
```plaintext
electron/resources/
└── app.asar
```
More details can be found in [Application packaging](application-packaging.md).
You can find more details on how to use `asar` in the
[`electron/asar` repository][asar].
## Rebranding with Downloaded Binaries
### Rebranding with downloaded binaries
After bundling your app into Electron, you will want to rebrand Electron
before distributing it to users.
### Windows
You can rename `electron.exe` to any name you like, and edit its icon and other
information with tools like [rcedit](https://github.com/electron/rcedit).
### macOS
#### macOS
You can rename `Electron.app` to any name you want, and you also have to rename
the `CFBundleDisplayName`, `CFBundleIdentifier` and `CFBundleName` fields in the

## Rebranding by Rebuilding Electron from Source
### Rebranding by rebuilding Electron from source
It is also possible to rebrand Electron by changing the product name and
building it from source. To do this you need to set the build argument
corresponding to the product name (`electron_product_name = "YourProductName"`)
in the `args.gn` file and rebuild.
### Creating a Custom Electron Fork
Creating a custom fork of Electron is almost certainly not something you will
need to do in order to build your app, even for "Production Level" applications.
Using a tool such as `electron-packager` or `electron-forge` will allow you to
"Rebrand" Electron without having to do these steps.
You need to fork Electron when you have custom C++ code that you have patched
directly into Electron, that either cannot be upstreamed, or has been rejected
from the official version. As maintainers of Electron, we very much would like
to make your scenario work, so please try as hard as you can to get your changes
into the official version of Electron, it will be much much easier on you, and
we appreciate your help.
#### Creating a Custom Release with surf-build
1. Install [Surf](https://github.com/surf-build/surf), via npm:
`npm install -g surf-build@latest`
2. Create a new S3 bucket and create the following empty directory structure:
```sh
- electron/
- symbols/
- dist/
```
3. Set the following Environment Variables:
* `ELECTRON_GITHUB_TOKEN` - a token that can create releases on GitHub
* `ELECTRON_S3_ACCESS_KEY`, `ELECTRON_S3_BUCKET`, `ELECTRON_S3_SECRET_KEY` -
the place where you'll upload Node.js headers as well as symbols
* `ELECTRON_RELEASE` - Set to `true` and the upload part will run, leave unset
and `surf-build` will do CI-type checks, appropriate to run for every
pull request.
* `CI` - Set to `true` or else it will fail
* `GITHUB_TOKEN` - set it to the same as `ELECTRON_GITHUB_TOKEN`
* `SURF_TEMP` - set to `C:\Temp` on Windows to prevent path too long issues
* `TARGET_ARCH` - set to `ia32` or `x64`
4. In `script/upload.py`, you _must_ set `ELECTRON_REPO` to your fork (`MYORG/electron`),
especially if you are a contributor to Electron proper.
5. `surf-build -r https://github.com/MYORG/electron -s YOUR_COMMIT -n 'surf-PLATFORM-ARCH'`
6. Wait a very, very long time for the build to complete.
