Focalboard is installed with Mattermost v6.0, where it's called Boards. To access and use Boards, [install or upgrade to Mattermost v6.0 or later](https://mattermost.com/get-started/). Then, select the Product menu in the top left corner of Mattermost and choose **Boards**.
Mattermost Boards currently uses channel-based permissions, meaning that only members of the associated channel can access (read/write) the boards for that channel.
Create or join a Private channel, Group Message, or Direct Message. Then, select the Boards icon in the channel header to create a board. Only members of the Private channel, Group Message, or Direct Message can access the board.
You can use the [share board](/guide/user/#sharing-boards) feature to share a read-only board with anyone (incuding unauthenticated users) who has the generated link.
