+### Installing node and corepack
+
+You can choose to let corepack manage the package manager version in use. Node is
+downloaded from `https://nodejs.org/dist`, and corepack either comes provided with
+Node, or will currently be downloaded from `https://repository.npmjs.org`, extracted
+and put into a `node` folder created in your installation directory.
+
+Node/corepack and any package managers will only be "installed" locally to your project.
+It will not be installed globally on the whole system (and it will not interfere with any
+Node/corepack installations already present).
+
+Have a look at the example `POM` to see how it should be set up with corepack:
+https://github.com/eirslett/frontend-maven-plugin/blob/master/frontend-maven-plugin/src/it/corepack-provided-integration/pom.xml
+or
+https://github.com/eirslett/frontend-maven-plugin/blob/master/frontend-maven-plugin/src/it/corepack-integration/pom.xml
+if you need to override the version of corepack in use.

+
+```xml

+### Running corepack
+
+If your `packageManager` specifies `yarn`, then you'll want to have something like:
+
+
+```xml
+<execution>
+    <id>install</id>
+    <goals>
+        <goal>corepack</goal>

+    <configuration>
+        <arguments>yarn build</arguments>
+    </configuration>
+</execution>
+```
+
+and if you're using `pnpm` instead, you'll want something like
+
+```xml
+<execution>
+    <id>install</id>
+    <goals>
+        <goal>corepack</goal>

 ### Running bower
 
 All bower dependencies will be installed in the `bower_components` folder in your working directory.
