+This is a repository for a Code Climate Quality plugin which is packaged as a Docker image.
 
-`codeclimate-sonar-php` is a Code Climate engine that wraps [Sonarlint](http://www.sonarlint.org) in standalone mode.
+Code Climate Quality is being replaced with the new [Qlty](qlty.sh) code quality platform. Qlty uses a new plugin system which does not require packaging plugins as Docker images.
 
-## Installation
-```
-make image
-```
+As a result, this repository is no longer maintained and has been archived.
 
-## Tests
-```
-make test
-```
+## Advantages of Qlty plugins
+The new Qlty plugins system provides key advantages over the older, Docker-based plugin system:
 
-## Usage
+- Linting runs much faster without the overhead of virtualization
+- New versions of linters are available immediately without needing to wait for a re-packaged release
+- Plugins can be run with any arbitrary extensions (like extra rules and configs) without requiring pre-packaging
+- Eliminates security issues associated with exposing a Docker daemon
