-## Background
-
-This action provides the features, as developed for https://github.com/dependabot/dependabot-core/pull/1848 (a PR for https://github.com/dependabot/dependabot-core/issues/733): **To have dependabot check cake-references**.
+## Goal
 
-Currently dependabot does not support this and sadly merging https://github.com/dependabot/dependabot-core/pull/1848 might take some time. In the meantime it is possible to use the code provided in the PR to do the checking "manually".
+The goal of this project is two-fold:
+- Enable users of dependabot to have a dependabot-like way to keep Cake dependencies up-to-date.
+- To keep the code for integrating Cake as a new ecosystem in dependabot up-to-date and tested.
 
-This action provides the means to do so.
+To that end, I have forked the original PR into a [custom repo](https://github.com/nils-org/dependabot-core/tree/cake/main) 
+where I try to keep the original code from [dependabot-PR 1848](https://github.com/dependabot/dependabot-core/pull/1848) up-to-date
+and error-free.

 ## Limitations
 
-This not a real dependabot, so there so "commands" to give (like `@dependabot rebase` and such). If you need to rebase the PR, you'll have to do that manually.
-
-TODOs:
-*  Check what happens when a PR is not merged and closed. Will it simply be re-created every run?
-* How to "ignore" dependencies?

+## Alternatives
+
+One alternative to dependabot is [Renovate](https://www.whitesourcesoftware.com/free-developer-tools/renovate/)
+which fully supports Cake. See the [post on cakebuild.net](https://cakebuild.net/blog/2021/04/cake-support-in-renovate) for a sample integration.
