If I try to add hello-world as described in the docs, I get:
$ ./bin/configlet sync --update --yes --docs --metadata --exercise hello-world
The `-e, --exercise` option was used to specify an exercise slug, but `hello-world` is not an slug in the track config:
/home/cwillner/projects/exercism/contribution/sqlite/config.json
But ./bin/configlet create --practice-exercise hello-world
worked just fine
