-#### Alert line `families`
-
-The `families` line, used only alongside templates, filters which families within the context this alert should apply
-to. The value is a space-separated list.
-
-The value is a space-separate list of simple patterns. See our [simple patterns docs](https://github.com/netdata/netdata/blob/master/libnetdata/simple_pattern/README.md) for
-some examples.
-
-For example, you can create a template on the `disk.io` context, but filter it to only the `sda` and `sdb` families:
-
-```yaml
-families: sda sdb
-```
-
-Please note that the use of the `families` filter is planned to be deprecated in upcoming Netdata releases. 
-Please use [`chart labels`](#alert-line-chart-labels) instead.

 #### Alert line `lookup`
 
 This line makes a database lookup to find a value. This result of this lookup is available as `$this`.

 Although the `alarm_variables` link shows you variables for a particular chart, the same variables can also be used in
 templates for charts belonging to a given [context](https://github.com/netdata/netdata/blob/master/web/README.md#contexts). The reason is that all charts of a given
-context are essentially identical, with the only difference being the [family](https://github.com/netdata/netdata/blob/master/web/README.md#families) that
-identifies a particular hardware or software instance. Charts and templates do not apply to specific families anyway,
-unless if you explicitly limit an alert with the [alert line `families`](#alert-line-families).
