+9. Supported Operating systems *os-support*
+
+Vim tries to support some old operating systems, however support for older
+operating systems might be dropped if maintenance becomes a burden or can no
+longer be verified.
+
+Here is the status of some operating systems. Note fully supported means,
+support is verified as part of the CI test suite.
