+# Compatibility
+
+We strive to make sure to stay compatible with the most recent NetBox version. Here you can see which version of Nazar is compatible with which version of NetBox.
+When major Ports to newer NetBox versions happen - which usually include breaking changes - the old version of Nazara will be moved to its own branch and tagged accordingly.
+Maintenance work on these older versions is not planned.
