+# Versioning
+
+It is recommended to use a stable version of the codebase. Major and minor versions follow those of Charon itself (i.e.: latest `v1.6.X` of CDVN will reflect latest `v1.6.Y` Charon), but patch versions in CDVN might be higher (i.e.: `v1.6.2` of CDVN has (latest) `v1.6.1` of Charon).
+This is done with mind, that small improvements on CDVN can be made without being tied to a Charon release.

 # Adding Validators
 
 Starting with charon v1.6, you can add validators to your cluster using the `charon alpha add-validators` command. Note that this is an experimental feature and should not be used in production (Mainnet). The example below is designed for the default configuration provided by this repository and assumes the stack uses the Lodestar validator client.
