# Plugins *The term 'Plugins' is referring to any types in Umbraco that are found in assemblies that are used to extend and/or enhance the Umbraco application. Plugins can also be added directly registered to their specific 'Resolver' if the plugin type is not public or if the Resolver type doesn't support finding types in assemblies.* What is a Resolver and what kinds of Resolvers are there? ## [Creating a Resolver for a Plugin](/umbraco-cms/reference/plugins/creating-resolvers.md) Creating a single object and multiple object Resolver. ## [Finding types](/umbraco-cms/reference/plugins/finding-types.md) Using the PluginManager to lookup types in assemblies to register in Resolvers. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
