+## Entrypoints
+
+This repository adheres to the
+[Scripts to Rule Them All](https://github.com/github/scripts-to-rule-them-all)
+standard: normalized scripts in `script/` are the entrypoints for the
+development workflow, and the Makefile targets are thin shims that call
+them. We provide:
+
+- `script/bootstrap` — install all dependencies (idempotent)
+- `script/setup` — make a fresh clone ready for development
+  (bootstrap, then install-precommit)
+- `script/projectname` — output the project name ("pixa")
+- `script/test` — run the test suite
+- `script/lint` — run golangci-lint
+- `script/fmt` — format all code (writes)
+- `script/fmt-check` — check formatting (read-only)
+- `script/check` — run test, lint, and fmt-check
+- `script/docker` — build the Docker image tagged via `script/projectname`
+- `script/cibuild` — CI entrypoint: `docker build .` (the Dockerfile
+  runs the checks, so a green build implies a green repo)
+- `script/precommit` — pre-commit checks (`go mod tidy` guard, then
+  `script/check`)
+- `script/install-precommit` — install the git pre-commit hook that
+  runs `script/precommit`
+
