groups:
  # DO NOT remove the default group, or shit will break
  default:
    priority: 0
    commands:
      - '[-]*'
      - '[+]msg'
  op:
    priority: 99
    commands:
      - '[+]*'
      - '[-]supersecretcommand'
    inherits:
      - default

(in the default configuration, the [+]* cancels out the [-]* rule made by default group for the op group. this needs to be done because the op group inherits the default group for educational purposes..!)

Each group has its name (i.e. default, op), priority and list of commands rules it has. You can customize groups however you want BUT you can't remove the default group.

To give a player a group, give them commandhide.group.<name> permission.

Command Rules

To allow a command use the [+] prefix, to disallow a command use [-] prefix.

Wildcards

Wildcards are allowed, so if you want to disallow all commands you can use [-]*.

Wildcards can be used with normal command rules to make a whitelist! (i.e. see the default group's default configuration; it disallows all commands but /msg!).

And they can be used to make a blacklist (i.e. see the op group's default configuration; it allows all commands except for the super secret one!)
