-### cfn2ts
-
-This tool is used to generate our low-level CloudFormation resources
-(L1/`CfnFoo`). It is executed as part of the build step of all modules in the
-AWS Construct Library.
-
-The tool consults the `cdk-build.cloudformation` key in `package.json` to
-determine which CloudFormation namespace this library represents (e.g.
-`AWS::EC2` is the namespace for `aws-ec2`). We maintain strict 1:1 relationship
-between those.
-
-Each module also has an npm script called `cfn2ts`:
-
-* `yarn cfn2ts`: generates L1 for a specific module
-* `lerna run cfn2ts`: generates L1 for the entire repo

-To update the CloudFormation spec, you can run `bump-cfnspec.sh` from a clean repo, as so -
-
-```console
-./scripts/bump-cfnspec.sh
-```
-
-If you wish to only update the CFN spec, make sure to install all dependencies and build the `cfnspec` module,
-and then you can just run:
-
-```console
-yarn update
-```
+This package has been replaced by a more modern version.
+Please use `@aws-cdk/aws-service-spec` ([source](https://github.com/cdklabs/awscdk-service-spec)) instead.
