# Plugins

Plugins are rules and sets of rules built by the community that support methodologies, toolsets, *non-standard* CSS features, or very specific use cases. Their *package* names are prefixed with "stylelint". Their *rule* names are namespaced so that they do not clash with stylelint's core rules.
