 Herokuish is made for platform authors. The project consolidates and decouples Heroku compatibility logic (running buildpacks, parsing Procfile) and supporting workflow (importing/exporting slugs) from specific platform images like those in Dokku/Buildstep, Deis, Flynn, etc.
 
-The goal is to be the definitive, well maintained and heavily tested Heroku emulation utility shared by all. It is based on the [Heroku:20, and Heroku:22 system images](https://github.com/heroku/stack-images). Together they form a toolkit for achieving Heroku compatibility.
