+The command <info>%command.name%</info> creates the following folders for migration usage:
+- src/AppBundle/ezpublish_legacy => Optionaly for extensions you want to version in your project source (as opposed to install using composer)
+- src/legacy_files/design  => Optionally for cusotm designs not already made part of an extension
+- src/legacy_files/settings/override => Folder for override settings for legacy
+- src/legacy_files/settings/siteaccess => Folder for siteaccess settings for legacy
+
+
+<info>src/legacy_files</info> stored in your root project for
+any design/extension/settings project files, and symlinks these into <info>ezpublish_legacy/</info> which is installed by composer.
+
+The benefit of this is:
+1. Being able to version your design/extension/settings files in git without versioning legacy itself
+2. A predefined convention for where to place these files when migrating from older versions
+3. Placing these files directly in ezpublish_legacy folder will lead to them getting removed in some cases when composer
+   needs to completely replace ezpublish-legacy package for different reasons.
