You don't have to install any other software. Packages are available on the releases page.

Detailed guides are available at docs.mattermost.com.

1. Download a file from the downloads page.
2. Launch Mattermost in the unarchived folder.
3. On the first launch, please input name and URL for your Mattermost server. For example, myserver : https://mattermost.example.com.

Ctrl or Command + Q to quit.

You can show the dialog from menu bar.

Configuration will be saved into Electron's userData directory:

• %APPDATA%\Mattermost on Windows
• ~/Library/Application Support/Mattermost on OS X
• ~/.config/Mattermost on Linux

A custom data directory location can be specified with:

• Mattermost.exe --args --data-dir C:\my-mattermost-data on Windows
• open /Applications/Mattermost.app/ --args --data-dir ~/my-mattermost-data/ on macOS
• ./mattermost-desktop --args --data-dir ~/my-mattermost-data/ on Linux

When you upgrade from electron-mattermost, please copy config.json from electron-mattermost. Otherwise, you have to configure again.

Normally, the application will follow your system settings to use a proxy, or you can set up a proxy by the following command line options.

• --proxy-server=<SERVER>:<PORT>
• --proxy-pac-url=<URL>

On Windows, please make sure to add -- before options. For example, Mattermost.exe -- --proxy-server=....

Our docs provide a guide on how to customize and distribute your own Mattermost Desktop App, including how to distribute the official Windows Desktop App silently to end users, pre-configured with the server URL and other app settings.
