### Configuration
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 -- --data-dir C:\my-mattermost-data` on Windows
* `open /Applications/Mattermost.app/ --args --data-dir ~/my-mattermost-data/` on macOS

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

### Proxy
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=...`.
