-The --filter flag format is of “key=value”. If there is more than one filter, then pass multiple flags (e.g., --filter "foo=bar" --filter "bif=baz")
+The *filters* argument format is of `key=value`. If there is more than one *filter*, then pass multiple OPTIONS: **--filter** *foo=bar* **--filter** *bif=baz*.
 
 Supported filters:
 
-- `until` (_timestamp_) - only remove containers and images created before given timestamp
-- `label` (label=_key_, label=_key=value_, label!=_key_, or label!=_key=value_) - only remove containers and images, with (or without, in case label!=... is used) the specified labels.
