+## Taskfile
+
+Another tool is configuration for [Task](https://taskfile.dev/). This repository
+offers a `Taskfile.yml` which contains standard tasks, like installing and
+running a linter.
+
+This `Taskfile.yml` can then be used by other projects. This has the advantage
+that you do not need to copy and paste Makefile snippets from one project to
+another. As a consequence each project using this `Taskfile.yml` immediately
+benefits from improvements made here (e.g. new tasks or improvements in the
+tasks).
+
+If you are new to Task, you may want to check out the following resources:

+- Instructions to [configure completions](https://taskfile.dev/installation/#setup-completions)
+- [Integrations](https://taskfile.dev/integrations/) with e.g. Visual Studio Code, Sublime and IntelliJ.
