@@ -12,11 +12,6 @@ There are three main Source packages:
 - [`@guardian/source-react-components`](../../libs/@guardian/source-react-components/README.md): A set of robust, accessible React components built using @guardian/source-foundations
 - [`@guardian/source-react-components-development-kitchen`](../../libs/@guardian/source-react-components-development-kitchen/README.md): The Development Kitchen is where new components and patterns can be cooked up, tested and shared. There are minimal acceptance criteria. It’s okay to duplicate and break things. If a Kitchen component proves valuable, it may be promoted to `@guardian/source-react-components`
 
-In addition there are two ESLint plugins:
-
-- [`@guardian/eslint-plugin-source-foundations`](../../libs/@guardian/eslint-plugin-source-foundations/README.md): ESLint plugin for Guardian projects using the `@guardian/source-foundations` package
-- [`@guardian/eslint-plugin-source-react-components`](../../libs/@guardian/eslint-plugin-source-react-components/README.md): ESLint plugin for Guardian projects using the `@guardian/source-react-components` package
