+## Update 3.0.0

+![SCAR-back](docs/source/images/scar-back.gif)
+
+Since version 3.0.0 SCAR creates a lambda layer called 'faas-supervisor' that is the core functionality of the lambda containers.
+This layer allows to deploy faster the new functions. The layer is created once (the first time that a function is created) and then it's linked by all the other functions.
+
+If a new version of the supervisor is released (e.g. when a new feature is added or a bug is found) the functions can be updated with the command `scar update -a -sl`.
+
+To check the supervisor layer version that your funciotn is using you only have to do an ls like `scar ls`
