 ## Help Welcome!
 
-There are plenty of things which need to be done. Some of these
-are listed in the [issues section](https://github.com/bemanproject/execution/issues).
-Other contributions are, of course, also welcome. Aside from contributing
-code the project welcomes reports on usage experience, code reviews, defect
-reports, features requests, etc. There are plenty contribution opportunities.

-If you want to contribute, you won't be left alone! Please e-mail

+# Contributing to `beman::execution`
+
+We welcome all constructive contributions! You will have something you
+can contribute independent of your level expertise!
+
+There is a huge range of contributions needed and welcome! Here is an
+incomplete list of starting points for contributions:
+
+* Some documentation is unclear.
+* There is some bug somewhere. That can be a typo in some documentation,
+   a logic error in the implementation, a deviation from the standard
+   specification, etc.
+* Something reference moved or the reference is out of date.
+* When compiling the code on your system warnings or even errors are
+    created.
+* The [issues page](https://github.com/bemanproject/execution/issues) lists
+    known issues.
+* The implememtation of a component may be missing.
+* The layout of some pages related to the project can be improved.
+* Some behaviour of a component isn't tested or documented.
+* You found something which should be linked from the
+    [resources](https://github.com/bemanproject/execution/docs/resources.md) page.
+* There are [pull requests](https://github.com/bemanproject/execution/pulls)
+    which could be reviewed.
+* This very page or list is lacking something.
+
+Whatever it is, you can improve the project! Ideally, create a pull
+request with your proposed change. If you think you can't do that
+for whatever reason, create an issue (if possible checking if the
+issue isn't reported, yet) explaining what should be done. You can
+possibly use a pull request or an issue to ask for help with something
+you want to contribute. You can also send a message to one of the
+contributors with your suggestion, e.g. to
+[Dietmar Kühl](mailto:[email protected]).
