The Gigantum Desktop app is a native app for managing the Gigantum Client, which is the actual web application you work in. Gigantum Desktop is the recommended way to install, update, and launch Gigantum Client, which runs inside a container.
If you prefer the command line, then you can instead install the Gigantum CLI. The Gigantum CLI lets you managed the Gigantum Client from the comfort of a terminal.
Downloading and installing Gigantum Desktop is pretty simple, and you can do this by following the instructions here. After Gigantum Desktop is installed, simply run the app to launch the client in your web browser.
Gigantum Desktop periodically checks for updates and notifies you when one is available. When updating, data is first downloaded in the background. That way you can keep working until you choose to restart, when the update will be applied.
To start the Gigantum Client, simply start the Gigantum Desktop app. Your default browser should open to http://localhost:10000, but if this doesn't happen then just go to that URL in a web browser.
You can manage the Client by right clicking on the icon in your system tray. To quit the application, just right click the icon in your system tray and select quit. This will shutdown the Gigantum Client and all Gigantum managed Docker containers. Be sure to save your work before quitting! If at any point you wish to simply restart the Gigantum client, select "Restart" from the app menu.
