 This registry provides:

+  workflows
 - A `testing-suite` group with a restricted `test-fetch` server
 
-Each server has the same base image but different configurations appropriate for

+Notice how the `devops-toolkit` group contains multiple servers that work

+deployment—demonstrating how groups can bundle related functionality.
 
 ### Run registry groups
 
 You can run entire groups using the group command:
 
 ```bash
-# Run all servers in the frontend-dev group
-thv group run frontend-dev
+# Run all servers in the devops-toolkit group (GitHub + Heroku)
+thv group run devops-toolkit
 
 # Run all servers in the testing-suite group
 thv group run testing-suite
 
-# You can also pass environment variables and secrets to group runs
-thv group run frontend-dev --env DEV_MODE=true --secret API_KEY=my-secret
+# You can also pass environment variables and secrets to specific servers in the group
+thv group run devops-toolkit --secret github-token,target=github.GITHUB_PERSONAL_ACCESS_TOKEN --secret heroku-key,target=heroku.HEROKU_API_KEY
