+## Marshaller and VDGS guidance for all sceneries<br> Jetway and object animation for custom sceneries
 One stop destination for DGS guidance, drop in replacement for legacy SAM, support for new custom sceneries.
 
 ## Installation and Support
+### Update from 4.x
+openSAM v5.x differs in it's file layout and a fresh install is recommended in order to avoid a lot of stale files.\
+If you changed the configuration files bring forward your changes into ```planes.cfg```.\
+AutoDGS is now included in openSAM. Copy over your airport configuration <xp_dir/Output/AutoDGS> to <xp_dir/Output/openSAM> .\
+In addition commands ```AutoDGS/...```  are renamed to ```openSAM/...``` so your your key and button bindings may need some rework.

 Per default all stands with jetways get a VDGS and all others get a Marshaller. This can easily be changed with the UI.
 First ensure that the plugin is activated then select the stand and change the setting accordingly. \
