+## Requirements
+
+We currently support running our linting tools on Linux and macOS. If you're developing on another
+OS, you can submit a [feature request][feature-req], or use our [clp-lint] workflow in your fork.

+To run the linting tools, besides commonly installed tools like `tar`, you'll need:
+
+* `curl`
+* `md5sum`
+* Python 3.8 or newer
+* python3-venv
+* [Task]
