+#### Changing the project information page index
+
+In case you want to change the index of `Project Information` page, you need to change it on the
+`project/ProjectIndexGenerator.scala` so it can be included in the automatic docs generation.
+
+#### License Report Generation
+
+By default, license report generation is disabled to improve compilation speed. You can enable it by configuring `-Dpekko.genlicensereport.enabled=true`. e.g.:
+
+- `sbt -Dpekko.genlicensereport.enabled=true "docs/paradox"`
+- `sbt -Dpekko.genlicensereport.enabled=true shell` And then `docs/paradox`
