 ⚠️ This executable has moved to [opentelemetry-go-build-tools](https://github.com/open-telemetry/opentelemetry-go-build-tools/tree/main/githubgen).
 
-This code is deprecated and will be removed soon. See https://github.com/open-telemetry/opentelemetry-collector-contrib/issues/37294.
-
-# githubgen
-
-This executable is used to generate the `.github/CODEOWNERS` and `.github/ALLOWLIST` files.
-
-It reads status metadata from `metadata.yaml` files located throughout the repository.
-
-It checks that codeowners are known members of the OpenTelemetry organization.
-
-## Usage
-
-```
-$> make gengithub
-```
-The equivalent of:
-```
-$> cd cmd/githubgen && $(GOCMD) install .
-$> GITHUB_TOKEN=<mypattoken> githubgen --folder . [--allowlist cmd/githubgen/allowlist.txt] 
-```
-
-## Checking codeowners against OpenTelemetry membership via Github API
-
-To authenticate, set the environment variable `GITHUB_TOKEN` to a PAT token.  If a PAT is not available you can use the `--skipgithub` flag to avoid checking for membership in the GitHub organization.
-
-For each codeowner, the script will check if the user is registered as a member of the OpenTelemetry organization.
-
-If any codeowner is missing, it will stop and print names of missing codeowners.
-
-These can be added to allowlist.txt as a workaround.
-
-If a codeowner is present in allowlist.txt and also a member of the OpenTelemetry organization, the script will error out.
-
