+Using JUnit Platform
+
+* Configuring JUnit Platform
+
+  To get started with JUnit Platform, you need to add at least a single <<<TestEngine>>>
implementation
+  to your project. For example, if you want to write tests with Jupiter, you must add the
+  <<<junit-jupiter-engine>>> to the dependencies like:
+
++---+
+<dependencies>
+  [...]
+    <dependency>
+      <groupId>org.junit.jupiter</groupId>
+      <artifactId>junit-jupiter-engine</artifactId>
+      <version>5.2.0</version>
+      <scope>test</scope>
+    </dependency>
+  [...]
+</dependencies>
++---+
+
+  This will pull in all required dependencies. Among those dependencies is <<<junit-jupiter-api>>>
which contains
+  the classes and interfaces your test source requires to compile. <<<junit-platform-engine>>>
is also resolved and
+  added.
+
+  This is the only step that is required to get started - you can now create tests in your
test source directory
+  (e.g., <<<src/test/java>>>).
+
+  If you want to write and execute JUnit 3 or 4 tests via the JUnit Platform add the Vintage
Engine to your projects'
+  dependencies:
+
++---+
+<dependencies>
+  [...]
+    <dependency>
+      <groupId>org.junit.vintage</groupId>
+      <artifactId>junit-vintage-engine</artifactId>
+      <version>5.2.0</version>
+      <scope>test</scope>
+    </dependency>
+  [...]
+</dependencies>
++---+
+
+* Provider Selection
+
+   If nothing is configured, Surefire detects which JUnit version to use by the following
algorithm:
+
++---+
+if the JUnit Platform Engine is present in the project
+    use junit-platform
+if the JUnit version in the project >= 4.7 and the parallel attribute has ANY value
+    use junit47 provider
+if JUnit >= 4.0 is present
+    use junit4 provider
+else
+    use junit3.8.1
++---+
+
+  When using this technique there is no check that the proper test-frameworks are present
on your project's
+  classpath. Failing to add the proper test-frameworks will result in a build failure.
+
+* Running Tests in Parallel
+
+  From JUnit Platform does not support running tests in parallel.
+
+* Running a Single Test Class
+
+   The JUnit Platform Provider supports the <<<test>>> JVM system property
supported by
+   the Maven Surefire Plugin. For example, to run only test methods in the <<<org.example.MyTest>>>
test class
+   you can execute <<<mvn -Dtest=org.example.MyTest test>>> from the command
line.
+
+
+* Filtering by Test Class Names
+
+   The Maven Surefire Plugin will scan for test classes whose fully qualified names match
+   the following patterns.
+
+   * <<<**/Test*.java>>>
+
+   * <<<**/*Test.java>>>
+
+   * <<<**/*Tests.java>>>
+
+   * <<<**/*TestCase.java>>>
+
+Moreover, it will exclude all nested classes (including static member classes) by default.
+
+Note, however, that you can override this default behavior by configuring explicit
+`include` and `exclude` rules in your `pom.xml` file. For example, to keep Maven Surefire
+from excluding static member classes, you can override its exclude rules.

+
+
+* Filtering by Tags
+
+You can filter tests by tags or tag expressions using the following configuration properties.
+
+    * to include <<<tags>>> or <<<tag expressions>>>,
use either <<<groups>>> or <<<includeTags>>>.
+
+    * to exclude <<<tags>>> or <<<tag expressions>>>,
use either <<<excludedGroups>>> or <<<excludeTags>>>.

 Review comment:
   I think we should indeed do that, cf. https://github.com/junit-team/junit5/issues/1425#issuecomment-390308206
