-# Plugin Portal
-
-This page contains a curated collection of official, partner, and community
-[Vault plugins](/vault/docs/plugins).
-
-For more information about plugin development, refer to this [documentation
-section](/vault/docs/plugins/plugin-development).  In addition, the [Custom Secrets Engines](/vault/tutorials/custom-secrets-engine) tutorial series demonstrates the plugin development workflow in more detail.
-
-## Official
-
-Official plugins are supported and maintained by HashiCorp.
-Unless indicated otherwise, these plugins are available directly in the Vault
-binary, but they can also be built and registered to Vault as external plugins
-if necessary.
-
-If a plugin exists separately under its own repository, follow the instructions
-within that repository to develop, test, and build the plugin. If a repository
-exists within the Vault repository, the plugin can be built as instructed in
-[here](/vault/docs/plugins#built-in-plugins).
