 ## Community maintained
 
-Community maintained devices are not under active development and support status is unknown to Armbian team. It represents combined former CSC (community supported configuration) and EOS (end of support). Can be removed from Armbian code base at any time. Left as a courtesy in case a community member wants to attempt to resurrect development.
