# Create master rule groups

Master rule groups can be used to install general rules for multiple exports. By using the master rule groups, you only have to create certain rules once. The master rule groups are applied to your source feed before it is manipulated in the *Categories- and Rules* steps of your feeds/API's. You can use the master rule groups for example to filter certain items from your feed or to set standard values.

### Creating the master rule groups

The master rule groups can be set up by navigating to "Master rules" in the left-hand sidebar.

You can create several sets of master rule groups. You have the option to choose which group of master rules you would like to use per export. By giving your groups different colors, it will be very clear which master rule group is being used in an export. The maximum amount of master rule groups you can create is 20 groups. Each group contains a maximum amount of 30 rules. For more information about these limits, you can [contact](https://www.channable.com/company/contact/) our support team.
