+With the secret option, you can make the result of the roll only visible to the game master, useful for Pathfinder 2e secret rolls or other similar situations. The GM channel must be set to use the secret option. You can set the GM channel using the `/gm` command. You may only use the GM command if you have the `Manage Server` permission.
 
 ### Roll Shortcuts
 
-You can also save rolls that you use often to allow you to reroll them quickly. These roll shortcuts are tied both to you and the server. This means that you can have the same shortcut on multiple servers and have them all be different rolls.

+#### Roll Groups
+
+What if you have a group of rolls that you often want to roll together? Enter the `group` command. This command builds on roll shortcuts by allowing you to group multiple rolls together. The `group` command is used to interact with roll groups.
+
+To create a new group, type `/group create`, press enter, enter the name, e.g. `perception checks`, and hit enter.
+
+To add a roll to the group, type `/group add`, press enter, enter the name of the group, e.g. `perception checks`, press enter, and type in the shortcut, e.g. `luceus-perception`. You can add as many rolls as you like to a group. If the group does not exist, it will be created, but the shortcut must already exist.
+
+To remove a roll from a group, type `/group remove`, press enter, enter the name of the group, e.g. `perception checks`, press enter, and type in the shortcut, e.g. `luceus-perception`.
+
+To view a group, type `/group view`, press enter, enter the name of the group, e.g. `perception checks`, and hit enter. This will display all the rolls in the group, similar to the `shortcut list` command.
+
+To list all groups, type `/group list`, and hit enter. This will display all the groups you have created and the number of rolls in each group.
+
+To delete a group, type `/group delete`, press enter, enter the name of the group, e.g. `perception checks`, and hit enter.
+
+You can roll a group by simply typing `/roll <group-name>`. This will roll all the rolls in the group and display the results. Note that, if you wish to roll a group, the group name must be the only thing in the input, otherwise the roll will fail.
