 `pytest-order` is a pytest plugin that allows you to customize the order in which
 your tests are run. It uses the marker `order` that defines when a specific
 test shall be run relative to the other tests.  
 
+Documentation
+-------------
+Apart from this overview, the following information is available:
+- usage documentation for the [latest release](https://mrbean-bremen.github.io/pytest-order/stable/)
+- usage documentation for the [current master](https://mrbean-bremen.github.io/pytest-order/dev/)
+- the [Release Notes](https://github.com/mrbean-bremen/pytest-order/blob/master/CHANGELOG.md)
+  with a list of changes in the latest versions
+
+History
+-------
 This is a fork of [pytest-ordering](https://github.com/ftobia/pytest-ordering).
 That project is not maintained anymore, and there are several helpful PRs
 that are now integrated into `pytest-order`. The idea and most of the code
 has been created by Frank Tobia, the author of that plugin. In case 
 `pytest-ordering` is revived, this project will be obsolete. 
 
-_Note:_ `pytest-order` is not compatible with `pytest-ordering` due to the
+Compatibility to `pytest_ordering`
+---------------------------------
+`pytest-order` is **not** compatible with `pytest-ordering` due to the
 changed marker name (`order` instead of `run`). Only the `order` 
 marker is supported, support for all additional markers has been removed for
 consistence (see [this issue](https://github.com/ftobia/pytest-ordering/issues/38)).

 Have you ever wanted to easily run one of your tests before any others run?
 Or run some tests last? Or run this one test before that other test? Or
