+The content of the SWC registry has not been thoroughly updated since 2020. It is known to be incomplete and may contain errors as well as crucial omissions.
+
+For currently maintained guidance on known Smart Contract vulnerabilities written primarily as guidance for security reviewers, please see the
+[EEA EthTrust Security Levels specification](https://entethalliance.org/specs/ethtrust-sl). As well as the latest release version, an
+[Editor's draft](https://entethalliance.github.io/eta-registry/security-levels-spec.html) is available, 
+that represents the latest work of the group developing the specification.
+
+General guidance for developers on what to consider to ensure security, that is currently maintained, is also available through the 
+[Smart Contract Security Verification Standard (SCSVS)](https://github.com/ComposableSecurity/SCSVS).# Title
