 ## Requirements

-- [Babashka](https://babashka.org/) for merging coverage reports (`script/coverage-report`)
-- Docker, for the integration tests only
+- Docker, for the integration tests and the `script/docker-*` tasks (all CI needs)
+- For running tasks natively (optional): [Clojure CLI](https://clojure.org/guides/install_clojure) (tools.deps) with JDK 11+, and [Babashka](https://babashka.org/) for `script/coverage-report`

 Each report directory has an `index.html` and an `lcov.info`. See
