-
-A template to create plugins for [vib](https://github.com/vanilla-os/vib)
-
-## Usage
-To use this template, simply fork it and change the module name in go.mod.
-
-Then you can modify the source in src/plugin.go to create your own plugin.
-
-We recommend adding the `vib-plugin` tag to your repo so that it can be discovered by other people.
-
-## Plugin requirements
-src/plugin.go explains all requirements for plugins with code examples.
-A short tldr:
-- vib requires `BuildModule(interface{}, recipe *api.Recipe*) (string, error)` to be available as it is used as the entrypoint for the plugin. Any other functions can be freely declared and will not be used by vib
-- Each plugin needs to have a custom struct for the module, with at least two mandatory values: `Name string` and `Type string`
-- It is recommended, but not required, to use the api functions for source definition or downloading sources
-
-## Building
-NOTE: Plugins will have to be compiled with the same go version as vib, for builds from vanilla-os, this version is 1.19, it is recommended to use podman/docker or the github workflow to build the plugins.
-
-Plugins can be built with `go build -trimpath -buildmode=plugin`, which will produce a .so file.
-To use the plugin, the .so file has to be moved into the plugins/ directory of the vib recipe.
-Plugins are only loaded when required, if a recipe never uses plugin example, example.so will never be loaded.
-
-This template contains a github workflow that can build the plugin with the right arguments automatically.
-Otherwise one can use podman/docker to build the plugin:
-`docker run --rm -v "$PWD":/usr/src/myapp -w /usr/src/myapp golang:1.19 go build -trimpath -buildmode=plugin -v`
+DNF has been added as a built-in module to Vib directly. So, this repository is no longer required.
